INGREDIENT GLOSSARY • Humectant
AT A GLANCE
The sodium salt of hyaluronic acid, a skin-identical hydration hero.
Sodium hyaluronate is hyaluronic acid plus a sodium atom; when you dissolve it in water, the sodium is replaced by a hydrogen from the water and it turns into hyaluronic acid. Hyaluronic acid (HA) is one of skincare’s most powerful humectants, able to hold onto 1,000 times its weight in water. It’s perfect for hydrating, plumping, and soothing skin.

As you can guess, hyaluronic acid is an all-star hydrator, drawing moisture to itself and hydrating the skin. In addition, it makes a great anti-aging ingredient: when it draws in moisture to the skin, that causes a plumping action that temporarily smooths the appearance of fine lines and wrinkles.
In addition, hyaluronic acid is actually an important part of getting active ingredients where they need to go. It can enhance penetration of those active ingredients through the stratum corneum, which functions as the skin’s defensive barrier against the world.
