Can Drinking Water Clear Your Skin?

July 12, 2021 0 Comments

When asked for their secret to flawless skin, many celebrities — including Jennifer Aniston, Gabrielle Union, and Beyoncé — claim that it has to do with their water intake. And although scientific research has established that hydration is a crucial part of maintaining overall health, you may be wondering: Can you really hydrate your way to healthy skin?

The Potential Link Between Drinking Water and Improving Skin

Although you’ve probably heard that swigging H2O can give you glowing, clear skin, robust scientific evidence behind this notion is lacking. One small study published in 2015 in Clinical, Cosmetic and Investigational Dermatology did suggest a relationship between hydration and skin health, though. Specifically, researchers found that in individuals with low daily water consumption — that is, those who were dehydrated to begin with — increasing water intake had a positive effect on skin appearance and helped maintain skin hydration levels.

But, the study notes, if you’re already well hydrated, drinking to a point beyond a balanced level of hydration may not have any additional impact. “Excessive hydration is unlikely to benefit the skin,” says Kathleen C. Suozzi, MD, director of aesthetic dermatology at Yale Medicine and assistant professor at Yale School of Medicine in New Haven, Connecticut. The skin is “hydrated” from the inside out by pulling fluid from the capillary blood flow in the skin, she explains, but if there isn’t enough water to pull from — say, if you’re dehydrated — skin can effectively dry out.

All the same, dermatologists including Dr. Suozzi say it makes sense to feature water in your healthy-skin routine.
