The acne cycle starts invisibly, below the skin'ssurface, weeks before a blemish breaks out. That's why Proactiv is designed to attack acne "proactively"—delivering the right combination of medicines and skin-care agents, in the right order and concentrations, to help control the acne cycle before breakouts occur. If you have acne, Proactiv Solution is the key to a clear complexion. Spot treating blemishes after they break out is too late—a frustrating, losing battle that does nothing for prevention. In contrast, Proactiv Solution treats the whole face—and neck, chest, shoulders and back as needed—in a way that helps to prevent breakouts before they even get started.
