Over the years, Obagi Medical Products has developed prescription-strength skin health systems focused on preventing and/or improving skin conditions including photodamage, hyperpigmentation (chloasma, melasma, and freckles), acne, vulgaris and rosacea. The Obagi Nu-Derm System consists of topical products, which when used as a system, result in substantial improvement to these skin related conditions. The Obagi Nu-Derm System is the number one brand of physician dispensed products in the United States. In April 2004, the Company continued its legacy as a leader in skin health systems, by launching a successful new system of products, the Obagi-C Rx System. As the first and only prescription strength Vitamin C and hydroquinone System, it has been a huge success with both patients and physicians.
