My TCA peels have always been done by my dermatologist, but I'm thinking about buying a 15% TCA peel and doing it myself. I read online that you have to neutralize the peel with baking soda or something, but my dermatologist has never had me do that. If anything, I'm not to wash my face for 6 hours after the peel. My question is, when I do the peel myself, do I have to neutralize it? does it matter?
