Proactiv is a popular skincare brand known for its acne treatment products. It was developed in the 1990s by dermatologists Dr. Katie Rodan and Dr. Kathy Fields. The brand offers a three-step system that includes a cleanser, toner, and treatment cream, designed to help reduce acne and prevent future breakouts. The key ingredient in many Proactiv products is benzoyl peroxide, which helps kill acne-causing bacteria and unclog pores. The brand has expanded its product line to include various formulations and treatments, catering to different skin types and concerns, making it accessible to a wide audience.
