11 Acne Treatments Our Editors Swear By — All Under $20

Item: Perricone MD Acne Relief Maximum Strength Spot Gel ($19)

What our editor said: "I found this tube in my drawer of skin-care products that I'm waiting to test and decided to give it a shot. The active ingredient in the treatment is two percent salicylic acid, but it also contains tea tree oil to calm skin and lactic and succinic acids to fight acne-causing bacteria. I dabbed a tiny bit of the clear gel on each of the pimples and went to sleep without too high of expectations. When I woke up the next morning, I really couldn't believe that it worked — the little whiteheads were gone. It doesn't work as quickly on deep, cystic acne (as to be expected), but I still dot some on to help speed up the recovery of those pimples, too. As for whiteheads, those are pretty much zapped overnight." — Jessica Harrington, associate beauty editor
