I've tried everything for YEARS that would help my mild adult acne and large pores/blackheads. Most creams were too greasy, salicylic products way too drying, and benzoyl peroxide bleached my skin. Since discovering that glycolic acid really WORKS for me, this is the best product I have found! It leaves your face feeling silky, hydrated and my pores are tight and clear to boot! If you have combination skin that is NOT sensitive, and you feel you are too old to have acne anymore (who spreads that lie that zits go away with puberty??? what a let down!) definitely get a sample of this product at your local Sephora and give it a try - if you like it, buy it on Amazon (definitely a better deal price wise). It makes a great base for your makeup and my skin is smoother and clearer than it's ever been (and i've only been using it 3 weeks!) Hopefully with a few months of use some of my perpetual blackheads will shrink up and disappear forever! Only downside - if you stop using it, like i did for a week, your skin quickly returns to it's former ways. But LOVE IT now!
