Sodium Hyaluronate


Sodium Hyaluronate

The sodium salt of hyaluronic acid, a skin-identical hydration hero.

Type of Ingredient


Why we use it

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.

Hyaluronic acid is found naturally throughout the human body, from skin to biologic fluids to connective tissues. Because it holds onto so much water, it works as a shock absorber (think like a gel pad in your shoes). In the skin, it helps keep everything plump, hydrated, and resilient.

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.
