How can women maintain healthy skin?

If the skin becomes dry and flaky, it can't effectively safeguard against the elements. Moisture and lipid retention is key. Since moisture moves upward to hydrate cells on the surface, it is important to clear the way.

Soap works fine to remove dirt. It does so by making fats soluble in water, which makes it easier for dirt to be washed away when you bathe. But harsh soaps damage the protective lipids on the surface layer. To preserve the waterproof layer, you want to avoid moisture meddlers that strip the natural protective layer and replace it with strategies that restore it.

Dr. Mehmet Oz, Vice-Chair and Professor of Surgery at Columbia University, offers this prescription for your healthiest skin:

• Add one-quarter cup olive oil to bath water;

• Use a gentle exfoliating scrub or cloth to remove dead skin;

• Use a mild body wash that contains replenishing oils that penetrate the skin;

• Don't use overly hot water;

• Pat dry after bathing, and apply a coat of moisturizer while still damp;

• Avoid ingredients that cause sensitivity, heavy fragrances, or dyes;

• Eat foods high in zinc and vitamin C to promote cell renewal.
