While drinking more water is no magic bullet, increasing your water intake will have a positive impact on your overall skin health – after all your skin contains 64 percent water.

Drinking an adequate amount of water daily is important for overall good health. Water aids in digestion, circulation, absorption and even rids the body and skin of toxins. Not everyone will agree that water consumption will improve skin… but it certainly can’t hurt. Many people often report that by increasing their water intake, their skin has a more radiant glow. Those who suffer from acne have reported the same results.

A 2007 study in the International Journal of Cosmetic Science took an in-depth look at the effects of long-term water intake on skin health. The study found that drinking 2.25 liters (9.5 cups) of water every day for four weeks altered skin density and thickness. A second study from the University of Missouri-Columbia showed that drinking 500 milliliters of water (about two cups) increased blood flow to the skin.

“I’ve found that water can have a significant impact in skin health,” says Dr. Steven Deliduka, board-certified dermatologist with Forefront Dermatology. “Without adequate water intake, skin appears duller, and wrinkles and pores more prominent. Proper hydration levels help the skin to become plump and improves its elasticity meaning it’s less likely to crack and have irritations and blemishes.”

Best Ways to Hydrate Your Skin

According to Dr. Deliduka, it’s best to be all-around proactive to keep your skin hydrated. “Don’t rely on just water intake to keep your skin healthy. A balance of skin care products and water will provide the best results.” Dr. Deliduka suggests applying a hydrating moisturizer immediately after showering. “After showering, the skin is still porous and vulnerable to products – allowing for better absorption,” commented Dr. Deliduka. As for the water intake, strive for at least 8 glasses of water a day to keep your skin hydrated and working properly.

Nothing will happen overnight, but even a good couple of weeks of increasing water intake should be enough for you to see how hydration affects your own skin.
