I have acne-prone skin, even still at 28 years-old. (Genetics are swell.) Anyway, I'm always on the lookout for any skincare product that will improve my acne without drying my skin out. (It's just a cruel joke to have acne and forehead wrinkles at the same time.) Anyway, I put this bad boy on last night and the first thing I noticed was the intense tingle. It feel like someone was blowing their Listerine breath on my face. (That was meant to sound more pleasant than it probably did.) It got a little intense, but once the product started to dry the intensity came down a notch. And after the rinse, I could SEE the tiny blackheads between my eyebrows had vanished. Long story short, this works. Be sure to throw a good moisturizer on overnight. You will wake up with brand new(ish) skin. You're welcome.
