I would say it has very mild AHA and BHA although the percentage is not stated. I experienced a little purging, and there was a tingling sensation during my first time applying it (my skin is sensitive). But in time, my skin has adjusted to it and now my skin is clearer and my pores are less noticeable. It works on my blackheads too. Was having hormonal breakouts recently and this thing works wonders calming the flared bumps all over. Never forget your suncscreen, though. I LOVE THIS!
