What Is Sodium PCA? The Hydrating Ingredient Worth Knowing
If you read ingredient lists, you've probably seen sodium PCA near the top of a few of them. It doesn't get as much attention as hyaluronic acid, but it's one of the most useful hydrating ingredients in skincare.
What it is
Sodium PCA is the sodium salt of pyroglutamic acid. Your skin already makes it. It's part of what's called the skin's natural moisturizing factor, a group of compounds in the outer layer of skin that help it hold onto water.
What it does
Like hyaluronic acid, sodium PCA is a humectant. It attracts water and helps keep it in the skin, so skin feels softer, smoother and more comfortable. It's lightweight and doesn't feel sticky, which is why it shows up in everything from serums to face washes.
Sodium PCA vs. hyaluronic acid
They work in a similar way and work well together. Hyaluronic acid is known for holding a large amount of water. Sodium PCA is a smaller molecule and part of skin's own moisture system. Many formulas use both to support hydration from more than one angle.
