What is the Difference Between Chemical Peels?
My freckles on my cheeks are getting darker and I also have a verticle scar on my nose that is 22 yrs old. I've been using the Obagi Nu-Derm & tretinoin combo, but hasnt given me the result I want. What is the diff between lactic/salicylic/glycolic/TCA peels? Which would be best for my condition?
