The Obagi System recognizes that your skin is a living organ with interacting functions. Restoring the health of your skin cannot happen if you merely treat the symptoms. To achieve (and maintain) skin health, you must correct the underlying problems and stimulate the growth of new, radiant, healthy skin cells. The Obagi Nu-Derm System meets this challenge with a daily program of five easy steps.

WARNINGS
 Caution: Hydroquinone is a skin bleaching agent that may produce unwanted cosmetic effects if not used as directed.
 Test for skin sensitivity before using by applying a small amount to an unbroken patch of skin and check in 24 hours. Minor redness is not a contraindication, but where there is itching or vesicle formation or excessive inflammatory response, further treatment is not advised.
 Avoid contact with eyes. In case of accidental contact, rinse eyes thoroughly with water and contact physician. A bitter taste and anesthetic effect may occur it applied to lips.
 Sunscreen use is an essential aspect of hydroquinone therapy because even minimal sunlight exposure sustains melanocytic activity.
 Treatment should be limited to relatively small areas of the body at one time since some patients experience a transient skin reddening and a mild burning sensation that does not preclude treatment.
 Pregnancy Category C
 Animal reproduction studies have not been conducted with topical hydroquinone. It is also not known whether hydroquinone can cause fetal harm when used topically on a pregnant woman or affect reproductive capacity. It is not known to what degree, if any, topical hydroquinone is absorbed systemically. Topical hydroquinone should be used on pregnant women only when clearly indicated.
 It is not known whether topical hydroquinone is absorbed or excreted in human milk. Caution is advised when topical hydroquinone is used by a nursing mother.
 Safety and effectiveness in children below the age of 12 years have not been established.
 No systemic adverse reactions have been reported. Occasional hypersensitivity (localized contact dermatitis) may occur, in which case the medication should be discontinued and the physician notified immediately.
