The acne cycle starts invisibly below the skin's surface 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.
