What Hydrolyzed Hyaluronic Acid does

Pulls water into the top skin layer
Helps skin feel smooth and hydrated
Adds moisture without a heavy texture

Hyaluronic acid is a sugar-like molecule that already lives in the skin, where it helps hold moisture. The hydrolyzed version is made by breaking the long chains into shorter pieces. Formulators use it because the smaller pieces can be easier to blend into light, watery products.

Like other humectants, which are ingredients that attract water, it draws moisture toward the skin's surface and holds it there. It is often found in serums, cleansers, and moisturizers. On the skin it feels light and silky, not heavy, and it can leave a smooth feel.

Good for

People with dry or dehydrated skin who want a light, water-based boost in serums, cleansers, and moisturizers.

Frequently asked questions

Is hydrolyzed hyaluronic acid the same as hyaluronic acid?

They come from the same family. Hydrolyzed hyaluronic acid is hyaluronic acid cut into smaller pieces. Both attract water to the skin's surface. The smaller form is often used in lighter products.

Does hydrolyzed hyaluronic acid work for oily skin?

Often, yes. Its light, water-based feel suits oily and combination skin. Because it draws water in, it works best under a moisturizer that helps keep that water from leaving the skin.
