Clearasil is the top-selling brand of skin care and acne medication, whose products contain chiefly benzoyl peroxide, sulfur & resorcinol, triclosan, orsalicylic acid as active ingredients. Clearasil has a wide range of products both for rapid and sometimes slow acne treatment and for everyday prevention.

Clearasil was invented in the United States in 1950 by Ivan Combe with the help of chemist Kedzie Teller.  At this time, it was the first dermatological brand created specially for younger skin to fight against pimples (acne). The active ingredients in the original product were sulfur and resorcinol, similar to the pre-existing adult acne product Acnomel.  Combe used the popular ABC television show American Bandstand to help promote the product and its superior smell.  In 1975, Wolfman Jacksigned a contract promoting the product Clearasil Acne Ointment
