My first chemical exfoliator. Great as an introduction for beginner or sensitive skin. Works well for a couple of months and then it didn't give the same effect as it used to. Help reduce blackheads, bumps, and prevent hormonal aches.

This product has its ups and downs...
Positive: cleans up my closed comedones, affordable.
Negative: Its a little spicy on my sensitive skin and pills easily

Would use at night, and use it sparingly. let it FULLY absorb before moisturizer, it will pill and sting if you use another product too soon after
