This was my first chemical exfoliator that I've tried. I went for the AHA because I had some whiteheads, and some spots from UV rays. I've been using this every other day or few times a week because my skin is on the sensitive and dry side. I don't see any huge difference so far after few weeks of using this but I've noticed that my skin is a lot smoother. I will continue to use this to see if there is a difference but so far, my skin has not reacted badly at all, no irritation or purging which is a good sign to me!
