The Obagi Nu-Derm System ... corrects surface discoloration and blemishes. Importantly, the Obagi Nu-Derm System also penetrates into the skin to stimulate skin cell renewal, improve circulation and help rebuild collagen. The normal barrier function of the skin is restored, making the skin less sensitive and better able to hydrate properly. The goal is to create soft, radiant-looking skin, to increase skin tolerance to environmental assault and to restore normal skin function… After six weeks (one skin cycle), new skin cells emerge to the surface.
This is the time in which the damaged top layer of skin is replaced by new a new layer of healthier cells. It takes about six weeks for a "newborn" cell to reach the top layer and exfoliate.
