Keeping skin healthy and glowing requires drinking enough water, says Anne Marie Tremain, MD, a dermatologist with Laser Skin Care Center Dermatology Associates in Long Beach, Calif. “It’s best to hydrate from the inside out,” she says. “Depending on your lifestyle you may need to adjust your water intake.” If you work out every day or are a caffeine fiend, for instance, then you’ll need to drink more., because workouts make you sweat and caffeine is a diuretic, which can dehydrate you. For smooth, moisturized skin, Dr. Tremain also suggests keeping showers short (less than five minutes) and using only lukewarm water as hot water can dry your skin out even more.
