I have very fine skin and have had crows feet since I was 18 years old!! I am 42 now and had Botox for the last approx 13 years, but obviously I've still loads of lines there from the years before I started of Botox.If I have a TCA peel, will it actually permanently get rid of, or soften these lines? i.e., Will I get a clean slate or are all my old lines deep within the skin and so will resurface?
