I've been getting chemical peels for acne scars. I got 2 light enzym peels and 1 extra strength enzyme peel. After how many peels will the scars heal?

Scars aren't removed. by peels. You can do them until the cows come home, and not see much difference other than exfoliation. So that's an expensive alternative that has been marketed to you. Cosmetic lasers that rebuild collagen provide longer lasting results, as scarring is occurring from the damaged collagen fibers that have created crater-like effects from contraction. Treat the cause, not the hype.
