DIY Vitamin C Serum

DIY Homemade Vitamin C Serum for health skin and wrinkle reduction

Vitamin C serum is a natural skin care ingredient that is often found in high-end beauty regimes, and Vitamin C serums, creams and lotions are popping up everywhere.

Why Vitamin C?

Vitamin C is touted as an anti-aging and anti-wrinkle cream. Many of these products also cost an arm and a leg. Thankfully, there is a natural, homemade and inexpensive alternative (noticing a trend here?) that seems to work just as well. Vitamin C is helpful for brightening and tightening skin (this works if you take it internally too!).

Vitamin C has been reported to:

Some cautions from experience:

  • Measure carefully and do not add extra Vitamin C as it is acidic and can/will burn the skin if the concentration is too high.
  • If you have extra sensitive skin, dilute with even more water
  • This is best paired with a skin care routine like Oil Cleansing
  • For dry or aging skin, this serum is a good solution. It can be used for acne prone skin too, but it seems that Sea Spray for skin works better.
  • If you are dealing with a lot of wrinkles or very dry skin, extra vitamin C can be added, but work up slowly and test on the inner arm before applying to the face

Vitamin C Serum Recipe

4.8 from 16 reviews
DIY Vitamin C Serum
Prep time
Total time
A simple and effective Vitamin C serum that boosts skin health with natural ingredients.
Recipe type: Beauty
  • ½ teaspoon natural real food Vitamin C Powder (I use this one)
  • 1 tablespoon distilled water OR 1 teaspoons distilled water to dissolve and 2 Tablespoons vegetable glycerine (I used this one)
  • a dark colored container to store (Vitamin C oxidizes easily) I used this one.
  1. Dissolve the Vitamin C powder in the water.
  2. If only using water and Vitamin C, you are done. This will store for up to 2 weeks or longer in the fridge.
  3. If using glycerine, dissolve the Vitamin C in the smaller amount of water, then stir in glycerine and store. This version will last a month or longer.
Personally, I like the pure Vitamin C and water recipe as a toner after cleansing, though glycerine is moisturizing and softening for the skin and will extend the recipe. DO NOT use glycerine on anything that is used in oral care or in the mouth as it is bad for teeth.

    can regular vitamin C powder, not crystals, also be used? Do you know how much is absorbed? I am trying to up my Vit C dose and am interested in learning more about transdermal recipes, especially the most absorbable ones with no harmful ingredients. Thanks.

    • Ilona says

      Hi Katie!
      I love your blog!! And use it a lot! Thank you so much!
      I have a question. From what I read, vit c is very unstable while dissolved and water-soluble which doesn’t allow it to get through lipid walls of the cells. In order to override those problems, the producers add all kind of stuff which make it so expensive.
      So, if we mix just water and vit c, do you think it still gets absorbed well? Your opinion ?
      Thank you

      • Laura Arrington says

        I understand what your saying and I am going to experiment with mixing the Vit C with Coconut oil that I have used for many 20+ yrs., the oil soaks deep into the skin (fyi; no one be-leaves im over 60) All the newest natural skin and hair receipts have “Coconut Oil” as the #1 best ingredient. Now after reading Dr. Oz statement of using Vit. C and Hyaluronic Acid together for an alternative to plastic surgery, and after his words was a free trial offer (+ shipping) that was running out on the night i happen to be reading it?(seen that trap before) I so love Katie’s receipt, and her caring for sharing with others, so i did take a copy of it… I think its only fair and my wish to share my years of knowledge. Would like to share my idea with Miss Katie also. like her opinion of using the liquid C (wonder what that is mixed with, in order to get it to mix with my oil?) Hope I have given you some answer’s to your concern, Laura

      • jean says

        where can I find ph 3.5 strips? I ordered Hydrion stiprs from amazon. They tested 5.5 in vit c and also distilled water. I am returning them

    • Claire says

      @mar: The best and most effective form of vit c to use is an ‘ultra-fine’ L-Ascorbic Acid powder, which can be found on ebay or places like LotionCrafter, etc, but a google search for ‘ultra fine L-Ascorbic Acid’ will easily help you locate an online suppler.

      The inclusion of ferulic acid and d-alpha-tocopherol (vit e) are what really add a punch and help vitamin c serums work so brilliantly.

    • robert says

      I use powder , one can be swayed by others believes,I use my own common sense along with research & intuition.absorbic acid is such .also one can bath with Epsom salts,bobs bakeing soda,ginger to open pores,absorbic acid/2000 to 4000 mg.powder & your choice of essential oils. Then, after ,apply the vit. C serum. Presto…

      • Sotirios says

        yes same proportion. In general L-ascorbic Acid is very unstable, light, temperature, humidity sensitive. So small batches every week or two.

          • Taurus says

            I live in Sweden the health supplies is very pricy here so I buy from the company Iherb. You can find vit c for very good prices there. Just make sure its L-ascorbic

      • davea0511 says

        There are different molecular compounds of vitaminc C, but as it turns out the most absorbable and beneficial is the easiest to make: L-Ascorbic. For that reason all vitamin C powder is composed of 99% L-ascorbic. Beware of those charging you more because theirs is “L-Ascorbic”, insinuating the other cheaper stuff is not.

  2. Ghada629 says

    This awesome!i have to try this as I do lot of aqua aerobic in chlorinated pool and was looking for ways to increase my vitamin c. Would like to all you though, if you don’t mind, which kind do you take orally? Is it the same powder and how much do u take from it?

    • Karen Davidson says

      I take Ester-C tablets (and also L-Lysine) by Solgar to aid in collagen production. They’re both great products to use! It’s great quality for the price & it’s easy on the stomach and releases over time, so you don’t just get a huge dose then excrete it through the urine.

  3. Michelle says

    I have Ester-C powder with Citrus Bioflavonoids by American Health. It is brownish-grey in color. Can that be used instead of the crystals?

    • Donna says

      No it can’t. Google. It will not absorb into the skin as well, although there is some implication it may help over the very long term with the deeper layers of skin. I am looking for immediate results, so perhaps a combo of both Vit C’s would be an option for you.

      • emily says

        i’m very confused by your comment. i googled homemade vitamin c serums and came across a blip on youtube from a dermatologist who advised against making them specifically because regular vitamin c is water soluble and supposedly does not absorb into skin well. he said vitamin c ester is better!

        • Dave says

          Then that dermatologist didn’t know what they were talking about. For one Ester-C is just as water-soluble as regular C, and no more fat-soluble, and besides all the research says regular Vitamin C absorbs better than any other type (including fat soluble variety ascorbyl palmitate). Ester C contains partially oxidized C, which doesn’t contribute metabolism boosting electrons. All the pros of Ester C vs regular C is entirely produced by the Ester C industry. All other studies find it’s efficacy no better and often worse than regular c.

            You are FULL of awesome goodness! Thank you for breaking that down for us!

  4. Helen Ellsworth says

    I just started using deep sean minerals,expensive (when you buy from the retailer) ebay it. wow wow wow, my skin is softer than it has ever been, I’m in my fourties,My combination skin is now under control, I no longer have servere oily T zone. I take Balckmore’s vitamin C to help from the inside out, my neck skin is improving amculatly. and only after nearly a week of taking VitaminC. :-)

  5. katalind says

    I find glycerine makes the serum very sticky. I currently use the recipe from gorgeously green and her recipe only calls for 1 tsp of glycerine and I can hardly stand the stickiness from that. I’m going to try using aloe Vera with my next batch.

  6. Elizabeth Resnick says

    I have been oil cleansing every since I read your post on it last January and love it. When I am finished there is some oil residue still on my face. Is it ok to use the c serum in top, or will the oil keep it from absorbing? I am anxious to try this!

      • Beth says

        I mix mine with coconut oil or pure aloe vera- works great! I also use the Hyaluronic Acid with vitamin C capsules. I can just use one at a time and not worry about it going bad. Just open the gelatin capsule and dump it and mix either aloe or organic coconut oil. ( I also use coconut oil as a makeup remover.

          • Lesa says


            I’m in BC also and have looked everywhere. I just bought mine from Bulk Actives online. I have the crystals from Choices but they are a pain to dissolve.

            I also use Hyaluronic acid and organic rose hip seed oil (natural retinol) in my serum and its amazing. The ultra fine l-ascorbic is so g=hard to find locally. I got 90g for 27 USD (shipping and all) bit pricey but it goes a long way.

      • Donna says

        Actually, the answer is no. Well, not ideally, because AA oxidizes the minute it hits the water, and so quickly, unless it is a fine powder that dissolves almost instantly, you will be losing all the healing power as you wait for the coarse powder to completely dissolve. I suppose if you want exfoliation……you could move a bit quicker? :-)

        • davea0511 says

          Actually the rate of oxidation does increase dramatically when it is dissolved (why you really should use dissolved C within 7 days), but oxidation rate is slower when crystalline because the individual crystals are not dissolved.

    • Lynn says

      I wouldn’t use crushed tablets as they contain excipients not wanted on the skin. Order a small container of NOW Foods Ascorbic Acid on Amazon. I’ve been taking it (orally) for 10 yrs. It’s good stuff & USP (pharmaceutical grade) which is important as you want purity….Good luck! I’m going to make my own and glad I already have the C on hand! I think I’ll make it with water and apply with cotton ball after I cleanse my face. Then, I’ll follow with my other skin care products, like moisturizer.

  7. MicheleStitches says

    Just so your readers know, I have made a similar serum, but had trouble with it being gritty. Then someone pointed out that I should put my C powder in a clean grinder (I have a coffee grinder I use soley for herbs) and grind it finer. That did the trick!

    • Cathy says

      Mine either. I even warmed up the water to dissolve it but then it recrystalised after it cooled down. I’m going to try and grind it like the suggestion above but any other suggestions would be great

        • Cheryl says

          I am using RO water, is that the reason the vitamin C won’t dissolve like it should? What is the difference in distilled and RO? If I shake the bottle long enough, which is a LONG TIME, it will dissolve. Also, I like the vegetable glycerin but it’s too sticky so I cut back on it.

          • Mary says

            Hi, I can think of three reasons why Vit C doesn’t dissolve – there is too much Vit C powder in proportion to water (add a bit more water); water is too cold (try it warmer or room temperature); Vit C powder is not fine enough (grind it to a fine powder in a blender or clean coffee grinder).
            I don’t use much glycerine, sometimes none. That’s OK.
            Hope this helps.

  8. Eileen says

    I use the peel from organic oranges, grapefruits and lemons, cut the peel and white into small squares and allow to dry for several days then grind into a fine powder…I add this to vinegar as a natural cleaner, I use it mixed with water for a facial toner, I add some to my breakfast for an extra boost of Vit C…the uses for your own homemade Vit C powder are endless!

  9. Shayna D says

    This is great but ascorbic acid is synthetic vitamin c and usually is genetically modified. I would worry that using this type of vitamin c could do more harm than good. You can buy a pure vitamin c powder that is organic and high quality for just a few dollars more.

    • davea0511 says

      Ascorbic acid is vitamin c and vitamin c is ascorbic acid. They are identical and the process for making it is always the same. Until this process was invented some 90 years ago it was extremely expensive and difficult to manufacture. There are a lot of marketing techniques used to try to make one sound better than another (like “organic”). Don’t buy the hype. Vitamin C is not a compound of substances that can be considered “organic” … it is a specific molecule that is the same whether synthesized or . Look at the vitamin C molecule on wikipedia – this molecule is what all vitamin C looks like that you can buy. Anything with a different structure is not vitamin C. There are buffered versions (ascorbates), and palmitates (bonded to a fatty acid), but what makes it all vitamin C is that 11 atom molecule to which these structures are attached.

  10. Jessica Hartnett says

    My crystals are not dissolving!! Please help. What could I be doing wrong? I’ve tried to mix with just water and with the glycerin.

    • davea0511 says

      crush with a mortar and pestle … do not heat up, if all will still not dissolve you may be at saturation point … pour off the liquid for use and throw out the left over sludge.

      • Zulfia says

        I dissolved 1/4 tsp vit C pow in 4 tsp water. It dissolved completely. But the moment I added 2 tsp aloe vera gel, it went pasty. Please help, what went wrong?

    • gail says

      I buy the vitiamin c jell caps and I poke a hole in it . It has the creamy color I was looking for the reg jell caps but didn’t have.I buy vitiamin e oil to mix with mine since it’s good for put on face and neck

  11. Monique Shantel says

    Thanks for posting this recipe! I have been using the serum for about a week now and my skin has never felt better! I made some for my Mom & she loves it too! :)

    • Mary says

      I’ve been using vit c serum for 3 months and haven’t noticed any difference to my face, or hands, although it did burn my neck. I’m 62 and wonder if I’m too old to get a benefit from vit c. Just not sure what % to use either.

      • Pat says

        I would also like to know the answer to Mary’s question as it pertains to me also. Is there a different way we need to apply it?

        • Pat says

          Is it possible to get an answerer to the question Mary asked about using the Vitamin C for 3 months with no visible results. I have been anxiously waiting for a post.

          • Mary says

            Hello Pat
            I’ve now been using this serum for about four months and have to say that I am now noticing a slight improvement. (I had acne scars so we weren’t starting with perfect skin.) I have also changed my cleansing routine. Here goes – I cleanse my face with Jojoba oil (but any light oil will do), wipe the excess off with a warm flannel and then apply the serum. For my neck I leave Jojoba oil on and apply the serum over it. I am not sure what % of Vit C I use but this is what I do. Mix 1 teaspoon Vit C powder with 2 teaspoons rosewater. If the Vit C doesn’t fully dissolve I add more rosewater. If the Vit C did dissolve first go, then I add more Vit C until it is at a stage where it doesn’t fully dissolve and I have to add more rosewater. This is called saturation point and the Vit C is at maximum %. (It helps if the Vit C has been ground into a fine powder – I use a blender to do this.)
            Hope this helps. Kind regards Mary

    • John Barry Gallagher says

      In the original research paper, the L ascorbic acid absorption dropped above 20% aqueous solution at ph 3.2 . The acidic ph is necessary to neutralise the charge on the ascorbic acid so it can penetrate the skin Most of the study used 15% but left it to soak for many hours fresh additions over 1 to 5 days saturated the skin, and after 4 days half of the addition had been lost without further applications.

  12. Angela Navarra says

    am I able to use a natural vitamin c powder derived from fruits? I’m hesitant to use L Asorbic Acid since it is usually derived from corn and genetically modified. Thanks for this post!

    • davea says

      All vitamin C is L-ascorbic, regardless of the source, and all vitamin C supplements are synthesized from the reichstein process regardless what you’ve heard or read. Vitamin C is a specific molecular structure of 11 hydrogen and oxygen atoms. Genetic modification has nothing to do with it’s structure. There is no genetic material in Vitamin C.

  13. Lesley says

    I made some of this. I see nowhere says how to use it. How do you apply to skin, leave on or wash off…instructions are needed

    • Meredith says

      This is an idea I might try. Those anti wrinkle promotion ads say they combine Vitamin C and Hyaluronic acid to remove wrinkles in two weeks. Guess which food contains mostly Hyaluronic acids? sweet spuds!

    • Stacy says

      Hi. I am using a store bought c serum that contains hyaluronic acid. I purchased ascorbic acid and hyaluronic acid powder with the intention of making my own c serum. I’ve been searching for a recipe that includes the two, and I still haven’t found one. I would love to know if there is an answer to your question. Thanks.

      • Lisa A. says

        I recently ordered both Hyaluronic Acid powder and L-ascorbic powder, hoping to make a mix of them too. However, what I’ve been reading online is to keep the 2 serums separate. Apparently, the Vit C needs about 10 min to soak into the skin, and it’s tricky getting the right % (5-20) figured out. Then, the Hyaluronic Acid serum is applied to help moisturize. If you mix them, the Vit C might be too strong or too weak and could waste the expensive Hyaluronic Acid. I guess I’m making 2 serums. Sigh. Hope that helps!

  14. alyssa says

    I make my own facial oil with jojoba, tamanu, and various essential oils. Any tips on incorporating vitamin c? I’m not too sure about how much I should add to my 1 ounce bottle and if I can just add vitamin c powder directly without diluting in water.

  15. Cheryl says

    Hi! Love all your recipes:) I don’t buy synthetic vitamins, but I do have camu camu powder on hand. Any idea if that would work? Thanks!

  16. Sandi says

    I just started using your DIY formula and bought the same ingredients you use. Truthfully I see no difference in the appearance of my skin but it has only been 4 or 5 days and it needs alot of help! My question is, no matter how much I mix the water and powder it does not seem to disolve completely, what am I doing wrong. I can actually feel some of the powder when I apply it.

  17. Priyanka Taj Khan says

    I m From India….So can u pls tell me where do we purchase the Vitamin C powder from???and in which form it is available in??? and also, i have a wheatish complexion but have tanned over the years…so will this help me get a brighter and fairer complexion???? thank u :) :)

  18. nadia says

    hey guys, i noticed a few people are having problems dissolving the crystals.
    add a tiny tiny bit of alcohol to the powder or crystal and it should help it dissolve quickly. It might get a little runny if you add too much so make sure you only add a bit. I used to work at a pharmacy and we used to make prescription body creams for people with skin problems, whenever we added crystal menthol or camphor crystals the only way to dissolve them properly was to add a bit of alcohol. Hope this helps and if anyone disagrees please do your research accordingly.

  24. emily says

    Hi, I was wondering if anyone knows of an alternative to distilled water for this recipe or just another way all together to make a vitamin c serum? I live in a place where distilled water is impossible to find and its very expensive to have it shipped to me. Thanks!

  25. Nina MC says

    Made it, Tryed it, Loved it, Making more. I justed used the water recipe. I used it on my 6 month pregnanat belly and face. felt great on both I put it on at night and took a shower in morning to rinse off. my face felt great for days. I also did the honey as a mask for 20 minutes a few days before the C. thankyou Katie for all the awesome DIY recipe been needing this in my life. ever greatful

  26. Vickie says

    The link for the one that you use “Vit. c” in the recipe takes me to Royal Camu. is this correct? or is it suppose to take me to an ascorbic acid? Thank you for responding~!!!

      • Chaser1 says

        I’m sorry Katie, I’m still confused. Even though I made a batch using Royal Camu, I’m still wondering if I should have used an l-ascorbic acid instead? I’m not sure the Royal Camu would be effective. Please let me know.

  27. Ellie says

    I absolutely adore your blog, thank you for existing! I have a question. My face has two tones due to excessive sun exposure (23 years living in Puerto Rico will do that to you) but overall it’s still a few shades lighter in color than the rest of my body, maybe because I take more of it. What can I use to even out my whole skin tone? Thank you very much for any help.

  28. Haley says

    Hey Wellness Mama! Cute name for a blog :)

    From what I have learnt in my travels vitamin c powder in its wholesome form could be irritating to some skins. Would it not be better to use L-Ascorbic Acid (the component of vitamin C that is beneficial to skin) ?

    The product you use sounds very interesting in itself though. Amazing amounts of vitamin C in it!

    Anyway, much like your blog. Thanks for the recipe. I shall attempt this once I get my L-Ascorbic in the post.


  29. Jill says

    Why do you have to use so much more glycerine than if you just used water? Wouldn’t the concentration be much less?

    • Julie says

      I agree with Jill. If you are using 1 T water, shouldn’t the glycerine option be “1 teaspoon water and 2 teaspoons glycerine?” That would make it a total of 1 tablespoon either way. I think 2 tablespoons glycerine and 1 teaspoon water would produce a much more diluted recipe.

  30. Mary says

    Asorbic acid is usually derived from corn, and anything from today’s corn always scares me. Do you know of any non-GMO brands?

    Thank you!! :)

  31. Cristina Gaston says

    Hi, this is a great recipe, thanks for sharing this. Can I make this recipe without water and just liquid vitamin c? That is, if I use liquid vitamin c, then I assume I won’t need water to dilute the powder? Please advice, thanks!

  32. Odysseia says

    The glycerine in this recipe is too much as glycerine tends to be sticky in larger quantities.
    I used 1/2 tsp. only and worked fine. Also, Aloe Vera gel is great to mix the Vitamin C with. BUT, Vitamin C tends to have a noticeable smell and when I applied it once on my body my husband asked me what smelled so strange on me…Blending in some essential oils helps to mask the smell.

  33. Brooke says

    Is it better to use this as a toner or the sea salt spray that is mentioned on your website as a toner?

  34. Mary says

    I can’t say I’ve noticed a smell from ascorbic acid but I do use rosewater instead of distilled water. My opinion is that the serum should have as few ingredients as possible (ascorbic acid, water/rosewater and a small amount of glycerine so that it is easier to apply to the skin. This is because the ascorbic acid can react with other ingredients, thus diluting its efficacy when applied to the skin.

    Hi, Thanks for this blog! iam using calcuim ascorbate crystals as a food supplement from Solgar, can I use this for vit c spray for my face and body ? 1/4 tsp provides,1300mg calcuim ascorbate, 1055mg buffered vit c? fortunately it seems to dissolve very easily in warm water, Many thanks- south africa

  36. Dee says

    I bought the ingredients, brought it all home and made a serum…I found as well, that is is a bit sticky, but I’ll use it at night. However, I went to my local organic food store, and not reading the label properly, most likely in haste or sheer excitement, bought the wrong stuff…

    What is the different in the L-ascorbic acid verses the calcium ascorbate I bought? (my serum oxidized before I got it into the bottle by yellowing too!) I used it a few times before it yellowed and it feels good on my face and once I get the proper flipping Vit C I will do this again! Thanks for the great recipes … Dee

    • Mary says

      My local health food shop sells brown bottles with dropper tops. Alternatively ask your friends to save their used small containers. As a last resort, we have shops that sell plastic containers of all sizes.

  37. Bianca says

    My spin on the above recipe: 1/8 tsp Vitamin C powder, 1/4 tsp orange blossom water (or rose water), 1/4 tsp squalane (purchased for $15 at local vitamin store) stored in amber bottle. I made very small quantities to try to ensure the stability of the Vitamin C. I make sure I give the bottle a good shake before application. My skin feels amazing soft after use and the water used imparts a terrific fragrance without having to use essential oils.

    I’m surprised by how many comments are being posted questioning the forms of Vitamin C, etc. I would think that women who were interested in DIY makeup would be a little more adventurous. Ladies, just experiment. Do patch tests on the inside of your arm if you’re worried but stay in the spirit of DIY and figure it out. Wellness Mama – your blog is amazing. I’ve tried several recipes and continue to enjoy your blog. Thank you.

  38. Kimberly says

    Does anyone have a good, natural, whole skincare regime for antiaging? It would really be nice to tie the oil cleansing and the vitamin c in with the rest of your regime such as for the eyes, a moisturizer and an exfoliator using all natural products.
    Thank you!

  39. Mariana says

    Hello, I have tried the vit C serum with ascorbic acid in the past but I decided to quit because I was getting wrinkles under eyes. From what I read this is what you go through at first and then it improves. I didn’t wait but quit because got scared. I feel like my mistake was that I had it too concentrated. Need to start with mild concentration and increase slightly every 2-3 weeks so that the skin gets used to it. Well, after I quit with the vit C and glycerin serum, I went on different products that didn’t do any good to my skin but actually made it worse. Don’t try too many products!!!! Even though is very tempting when you see something new on the shelf in the store that looks very promising, don’t do it!!! Now I ended up with spots, acne and dehydrated skin. I pushed all those products away and started all over the process of repairing my skin. I found out that parfums, alchools and dyes are the skin enemies because they dry out and irritate the skin, so I bought the avenoo foam cleanser that doesn’t contain fragrance and any kind of alcohol and use it on a washcloth morning and evening. After I cleaned the skin, I need to give it some vit. C. I smash a strawberry really well and apply all over the face for 15-20 min. The mask I do every other day. Strawberries contain also salicylic acid which helps with acne and other good things which help tighten, cleanse the skin and brighten it. I wash the mask off with lukewarm water. Pat dry and then apply moisturizer. My moisturizer is now made of a drop of vegetable glycerin in the palm of my hand and add water as it can hold so it doesn’t spill. I found that if I make the mixture of glycerin and water for a week or two it goes bad and I waste a lot. So I just make it right before I apply it. It is so quick and easy. I apply all over the face and that’s it. Hydration provided!!! Now I struggle with myself to apply sunscreen when I go outside just don’t like the consistency of it! But I see that the results of this natural products routine has improved the color and my skin is more hydrated than before. Rarely now I have blackheads. My acne scars are fading slowly! I will stick to this routine and just wanted to share with you my experience maybe someone that didn’t go through this will benefit. This is cheap and not harmful to the skin. I spent a lot on creams and cleansers that made my face feel tight. If anyone tries this routing please write and let me know how it works for you! Wish you all good skin!!

    I wouldn’t use a spray bottle for Vit C serum. The spray will discolour anything it touches, clothes, walls, floor. The stain does wipe off but in the meantime it leaves a dirty yellow colour.

    Hi OCM is beyond amazing! May I ask a question, I read one can add a pinch of Epson Salt to the oil, why and is is beneficial??
    Thanks again for this amazing site, believe it or not I read every single comment, because most of the questions are already dealt with!
    Thanks Katie

    Dry but. C is shelf stable for up to a year, but once in a solution it breaks down in just over 2 days. How do you stabilize it?

    • John Barry Gallagher says

      Thc original research paper which i poster the referenve used a comination of zinc hylauronic. Acid and some complex buffers to stabilise during the course of the application (24 hrs) , all not easly available. I am afraid. However, if you go to the linnus pauling institute site and click skin health it will reference other stabilising methods from peer review research using natural products. Of which the name escapes me

  43. Mary Hall says

    Hi, I apply a light oil (you can use any moisturiser) to the sensitive parts of my skin first. This helps reduce stinging. Your skin will get used to Vit C but, as suggested, you could also dilute your Vit C.

  44. john says

    how often shud you use this vit c serum everyday? do u no the ph level of this? thanks do you notice a diffrence in your skin since using it?

  45. Heidi says

    Hi Katie – I love your site and refer to it all the time! I’ve been making this serum for a few weeks now and wonder if using witch hazel instead of water would work? Or is there any reason this should be avoided? Thank you!

  46. maria says


    I rant and rave about your site all the time!!! I’ve bought the brand you gave as an example, and now realize you wrote powder, but showed crystals. Which is best to use?


  47. Beth says

    I bought hydralauric-vitamin C capsules. I empty one or two at a time and add water, It’s a little gritty so I use it at night. I’m going to try grinding it in a mortar/pestle. It’s enough for a couple days using it on face and neck. Last night I added coconut oil.

  48. Deirdre says

    I used the Mortar and pestle to grind my Vit C . It seemed to decrease the grit a little and I make a small bit at a time, and have used Glycerine and I have used rose water and both separately…I also found that you should wear old clothes and cover your bed sheets…Night time is best…lol…keep the updates coming love to read about how others are able to create…Cheers…Dee

  49. Amy says

    I’ve been using this exact recipe for 6 months and it works great!! I notice if I don’t use it for a little while, my skin gets dull. I use the distilled water and the glycerin. It takes around 15 minutes to dissolve the crystals in the water. I put it in a glass measuring cup and stir with a plastic straw. Stir, stir, stir!! Then add the glycerin and mix until smooth. Use a small funnel to pour into amber glass dropper bottles. I have 5 of my girlfriends addicted to it, I make it for them. I also use it on my chest and back of hands, as it makes a good amount for 30 days. We are all 38 years old and up, notice results, and no irritation or burning!!

  50. Sally says

    Can I crush vitamin c pills to use?also does the vitamin c have to be acidic?I saw buffered c powder but was not sure if that would absorb help need answer a!

  51. Dani says

    my grandmother simply used lemon or lime juice mixed with olive oil, and sweared by it. is this the same vit c and was it absorbed by the skin?

  52. MAUREEN says

    I have been using Ascorbic Acid mixed with Reviva Labs Rosewater facial spray. the spray contains distilled rosewater, glycerin and hydrolic acid, and some other beneficial ingredients.
    The C desolves without much difficulty.
    The problem is it seems to leave a film on my skin that makes me wonder if it is indeed penetrating the skin or simply sitting on top of the surface of it. I thought it would be a good combo. I’m currently using a 15% recipe.
    Should I try the original recipe instead? Has anyone have the problem of a hardish film being left on top of the skin?
    It stings a little too but not that bad. Its the “film” left behind that leave me concerned about absorbtion.

    Thank you, Maureen

    I have been making this for years.. But I have found that glycerine is just too sticky..

    So I substitute Jojoba oil.. which is the closest oil to our skins own natural oil..

    And it works beautifully.. I’m 73 and am taken for 50.. And this Serum is the key… So Keep it simple girls and don’t add anything else, 3 ingredients is all you need.. and give it time, it is not an instant fix.. Every ones skin is different, it may take some of you longer to see results..

    I have found that the ideal time to use this serum is at least 1/2 hour before you go to bed.. (to give it time to absorb).. In the morning rinse your face with filtered water (never use tap water on your face) and then use your moisturizer…

    Speaking of your moisturizer, you can add a little of your serum to it for daytime use.. (put a little of your moisturizer in the palm of your hand and add 1 or 2 drops of your serum to it and blend..

    And girls.. Never Ever use sunscreen.. It is full of harmful chemicals..
    There are natural substitutes.. Frankly, the only time you really need sunscreen is if you are spending a lot of time outdoors.. But for most of us that are just going to the store and in and out of the car running errands or going to work.. You really don’t need Sunscreen.. In fact the vit. D you get from some exposure to sun is healthy for you and your skin…

    Hope this helps..

    And to our Wellness Mama, that gives us all this wonderful info with her generous Heart.. Thank-You for all the time and effort you give to others.. you are a Blessing…

    • Lola says

      Hi Patricia

      That’s very encouraging, thank you :).

      Do you really mean three ingredients, or four? Ascorbic acid, Jojoba oil, water and…hyaluronic acid? Also doesn’t there need to be a fifth ingredient to emulsify the Jojoba oil? How do you get the oil and water portions to blend?

      I also get Maureen’s film-forming problem. Doesn’t mater if I use water or aloe, glycerine or no glycerine, I still get a kind of dry film that makes me doubt penetration. This only happens with ascorbic acid serums. My other serums in the same HA base are fine.

      Thank you :)

    • Jason says

      Can you please share your recipe? I used to make 1/2 tsp of l-ascorbic with 1 tsp of aloe vera, but I didnt see difference.

  54. Lewis says

    Hello! I really want to try this Vitamin C serum, but the problem is – I don’t have no access of vegetable glycerine :( I have read somewhere you can use Aloe Vera gel as a substitute? Can you use it? Thanks!

  55. rake says

    Hi everyone,

    I have been using the ascorbic acid serum on my face for a week now, and I have noticed some tiny pimples on my forehead. Did anyone else experience this? Should I stop with the serum?

  56. Kate says


    My naturopath suggested that I use a Vitamin C (or E) based cream to combat the thinning skin under my eyes (which make the veins there more noticable and aging). After some internet research I decided to go the DIY route with your serum. I’ve been using it for about a week, and I noticed this morning that there are a lot of fine lines around my eyes that weren’t there before! Has anyone had this problem with the Vitamin C serum? Should I adjust something in the recipe? Should I stop using it under my eyes and just use it at the corners where the veins are? Or should I just get more sleep? It’s a bit distressing, as everyone says so many good things about this serum!

    Thanks for any help!

    • Trisa says


      Since that skin around your eyes is so sensitive.. I would suggest that you use
      the C serum just on your face.. and use Vitamin E around your eyes..
      After a couple of weeks try mixing a little C serum with the Vitamin E and see how
      your skin reacts..

      We are all so different, so don’t fret..
      Let us know how things go..

  57. Lynn says

    I’ve been using the DIY C serum for about a month & I’m not impressed. I also think my eye area looks worse…Not sure what this is all about…

  58. Natalie says

    I have a purchased serum that I love, but I’ll be doing DIY once it’s used up – so much cheaper and fresher. It’s so easy to make with water – you can make a small amount fresh every day, with tap water and use as a toner. If you want your small supply to last longer, you can add a tiny bit of grapefruit extract or Vit E oil. If your serum changes colour or develops an off odour, throw it out.
    It should be the first thing you apply to a clean face, before other serums and moisturizers.
    I have definitely noticed a difference in smoothness and clarity.
    I’m just going to use a smidge of glycerine or else aloe vera juice. I think the idea of rose water (for dry skin) or witch hazel (for oily) is a good one.

  59. Melissa says

    Planning to try this. This blog has been helpful,thank you.
    One question, tho: do not find anyone answering clearly the question about
    combining hyaluronic acid with this to enhance absorption.
    Does anyone know if that can work,combining it into this serum?
    Or would one need to make separate hyaluronic serum as some
    other sites suggest? Or is advice to leave it out entirely? Thanks for
    any input before I go forward with concocting my serum.

    • Trisa says

      Hi Melissa

      Concerning your question as to whether or not to use Hyaluronic Acid…

      First off you didn’t really specify what type of HA you want to use..

      But just make certain that the HA you use is of low molecular weight, otherwise the skin just
      can’t absorb it.. (Not all creams use this).. The low molecular weight allows the HA to penetrate
      the skin, rather that just sitting on top..

      Also make certain that you don’t use more than 1% in your serum.. Once you have
      made this use sparingly and judge how your skin responds..

      The main purpose of using HA is that it helps your skin retain water.. And as a result, many have
      found that it has helped their skin look more youthful.. But it doesn’t work for everyone..

      And if you find Melissa that you don’t see any improvement in a couple of weeks.. Try adding a
      a drop or two of lavender oil to your mix before giving up.. It may help…

      Frankly I find that simple mixes without a lot of ingredients, are the best DIY treatments we can
      use for our skin.. And don’t forget that some of the best ingredients are right in your own

      It would be nice to know how this works out for you Melissa.. So keep us posted…

  60. Lynn says

    I truly think it’s best to omit any oil & just mix the ascorbic acid with water. The skin absorbs all the C & when dry, I then use my moisturizer. Otherwise, too goopy & then moisturizer can’t absorb. Make sense? I think so.

  61. Jason says

    I’ve been using this formula for about 4 weeks now and am absolutely amazed by the difference in my skin. I’m a 41 year old male from Australia and have enjoyed way too much sun in my life….spent all spare time at the beach, with my face and arms displaying the ravages of the sun. My hands and forearms are already looking much firmer and pigmentation has reduced. As for my face, the skin is feeling firmer, more hydrated and also the pigmentation spots have reduced significantly. The serum as described is a sinch to make and I’m committed to using it into the long term. GUYS…..get to looking after your skin with this wonderfully simple, effective and inexpensive product. Thanks a million wellness mama ;-)

  62. Betty says

    Just watched doctor OZ last night telling about the help of Vitamin C and E creams in Australia I have found there is no vitamin C cream but have bought Vitamin E oil pure thank you for the Blog am taking C orally
    hmmm my age is 83

  63. Cheryl says

    Hi.. im just new here.. i’m very interested to try this serum.. I just want to know how to use this.. Is it okay to use this overnight in the face? And is it safe if I use Tretinoin & Hydroquinone first and then apply the vitamin c serum overnight? Please advise asap.. Thank you..

  64. Harpreet says

    Hello, I did some research and found out that 3 components that increases the absorption of Vit C are:
    1) Type of Vit C- Ascorbic acid and L-ascorbic acid are the most effective ones
    2) Concentration- 20% Vit C has the highest absorbancy rate
    3) pH- It is best absorbed at the pH of 3

    I was wondering if this recipe satisfies all these components?
    Thank you!

  65. Jeni says

    I have read of all the benefits of vitamin C for the skin and really want to try this serum, however I’ve also read that glycerin works by drawing moisture from around it. If you are in an area with 65% or higher humidity it will draw moisture from the air and lock it into the top layer of skin. But if humidity is less then it will draw moisture from the bottom layers of your skin :-( Is there an alternative to glycerin for this recipe? I’ve heard Aloe is a good one but I’m not a huge fan of the feeling of Aloe. Any suggestions?
