Hyaluronic acid is the key to instantly plumping fine lines and making skin look glowy. It can be found in everything from serums to sheet masks and even injectables—but what exactly is it? We asked dermatologists to give us the 4-1-1 on hyaluronic acid, including the right way incorporate it into your skin care routine.
What is HA?
Hyaluronic acid (HA) is a sugar found naturally in our skin that holds water and helps keep it hydrated and plump. The HA within our bodies holds a thousand times its weight in water to not only retain all that moisture in our skin and joints, but also prevent all that moisture from evaporating into the air, according to Dr. Lily Talakoub, a dermatologist at the McLean Dermatology and Skincare Center.
Just like collagen and elastin, the amount of naturally-occurring hyaluronic acid in our bodies decreases as we get older. There are, however, ways to help stimulate production of HA in our bodies. “Diet affects the skin significantly,” says Dr. Howard D. Sobel, a dermatologist in New York City. “Eating fruits and veggies with lots of antioxidants protect the skin from inflammation in turn helps the skin retain it.”
