Good morning and thank you for your question! After a chemical peel your skin is going to be sensitive, especially to more potent ingredients and products. Vitamin C can be very stimulating and which can make your skin feel a burning sensation resulting in redness. I would recommend using only gentle products with calming ingredients (chamomile, lavender, aloe, etc.) until your skin is completely done healing. Make sure to keep the skin moisturized and always wear sunscreen. Try consulting with a skin care professional for more information on the right products to use during the healing process and thereafter. For more information please feel free to look at our website.
