Thank you for your question. Whether or not you can wear makeup one day after a chemical peel will depend on the depth of the peel. A light peel only affects the superficial top layer of the skin, and therefore it is probably safe to wear makeup after a light peel. Medium and deep peels penetrate deeper into the skin, dissolving away the protective outer layers and exposing healthy new skin underneath. However, that healthy new skin needs time to heal, and putting makeup on can not only irritate this delicate tissue, but also put you at a higher risk for infection. As such, I recommend that you wait at least a week before wearing makeup after a medium or deep peel. With all of that being said, you should consult with the experienced person who is performing your peel. They can give you more specific answers according to your skin and the type of peel you have chosen. Best, Dr. Verbin
