Our reVive Light Therapy® Essentials for Acne destroys acne-causing bacteria fast. You’ll see results within days! The Essentials Acne acts as an acne spot-treatment device using non-UV blue light. Blue light reaches deeper into your skin and pore layers than topical acne treatments, and the light destroys acne-causing bacteria while reducing sebaceous glands' oil production. Red lights minimize acne- related inflammation, a primary cause of scarring. The result is clean, clear skin with a healthier appearance.
