AHA is for surface exfoliating, however it might work in your acne too, because it renews and unclogs your skin. I've oily very pimples prone skin and BHA by no means labored for me, but AHA did. There aren't any age restrictions for the usage of these products, so a Retinol based mostly cream is quite acceptable for a young person who's having pimples problems. Apply 2.5 % benzoyl peroxide directly to the zits.
