Proactiv Solution is an over-the-counter topical treatment for mild to moderate forms of acne, widely known for being marketed in Guthy-Renker infomercials since 1995. Like many acne treatments, the active ingredient is benzoyl peroxide, along with other ingredients such as moisturizers and exfoliants.

Proactiv was developed by California dermatologists Dr Katie Rodan and Dr Kathy Fields.

Proactiv Solution was created to treat mild to moderate cases of acne. However, it is not guaranteed that the user will ever see results. Like most antibacterials for treating acne, Proactiv Solution uses benzoyl peroxide as one of the main active ingredients. Reportedly, Benzoyl peroxide may cause dryness and peeling of the skin; approximately 5 percent of the population is allergic to it. Reported reactions include redness, itching, hives, swelling and a burning sensation after topical application. Benzoyl peroxide may also cause increased sensitivity to sunlight and induce color-specific discoloration of clothes. For those who may be sensitive or allergic to it, Proactiv Solution has marketed the Gentle Formula kit, containing salicylic acid instead, although it is unclear whether or not salicylic acid can also cause these side effects.
