Acne occurs when oil and dirt become trapped beneath the skin. The BHA sloughs the outer layer of skin so oil and dirt have less chance of being buried. Another way to exfoliate is to mix a tiny bit of kitchen baking soda with your regular cleanser and
gently massage into the skin. It really does work wonders. If the skin seems irritated at all, then cut back on the frequency. Sometimes you have to play around with how often you exfoliate. Also, it's imperative to wash the face twice a day.
