Hydration begins within. If you want your face to glow, drink your water. Elson Haas, MD, founder and director of the Preventative Medical Center of Marin in San Rafael, Calif., and author of The Detox Diet (Celestial Arts), recommends downing at least two full liters of purified water on a daily basis. Shogo Mochizuki, author of several books including Japanese Facial Massage and Anma: Traditional Japanese Massage (Kotobuki Publications), concurs. "Even oily skin can become dehydrated and flaky if you don't drink adequate amounts of water," he says.

Mochizuki also believes that when applying topical moisturizers, the method of application is as important as choosing the best product for your skin type. "Massaging the moisturizer deeply into the skin, paying close attention to specific acupressure points in the face," he says, "will stimulate nerves, create improved lymph drainage and effectively tone and condition the facial muscles."
