Im on week 19 of the regimen, and seem to have hit a plateau kind of effect. Ive discovered witch hazel and it piqued my interest. From what ive read on reviews here on acne.org, it seems to do the same stuff that AHA+ can do, like clear blackheads. Should i try it, or will it interfere too much and make me worse since im on the regimen? Any feedback or experience with it? Thanks in advance!
