Should ZO® Skin Health be used instead of Obagi Nu-Derm?
While the two brands share the same philosophy, and were both developed by Dr. Zein Obagi, ZO® Skin Health is a cosmeceutical line (sold without a prescription) and Obagi Nu-Derm contains prescription-strength ingredients, and is therefore physician-dispensed. Together, the two brands complete what Dr. Zein Obagi calls “the circle of health”–a program for a lifetime of healthy skin. ZO® Skin Health can be used as a prequel to Obagi Nu-Derm, in conjunction with it, or as part of the Nu-Derm maintenance program..
