Place oats in a blender and pulse for about 30 seconds, until the consistency resembles a coarse powder.
Transfer it to an airtight container with a lid.
Just before scrubbing, mix 1 teaspoon ground oatmeal and a few drops of water until the mixture is spreadable. Add olive oil or honey, if desired.
Apply the mixture to your face in small circular motions, avoiding the eye area. Gently rub into your skin for about one minute, then rinse with a warm, wet washcloth. Pat your face dry.
