Proactiv Solution 3-Step System
Top-rated acne-treatment kit
Proactiv Solution 3-Step System contains cleanser, toner and lotion. The system uses benzoyl peroxide, a proven topical disinfectant that kills acne-causing bacteria. Both the cleanser and the lotion contain a 2.5 percent solution of benzoyl peroxide, which several experts prefer because it is less drying than higher concentrations but is just as effective. The toner uses glycolic acid, an alpha hydroxy acid that exfoliates the skin. While many users swear by Proactiv, we also read some reports that while it's effective at first, its effectiveness can weaken for some users over time.
