Hydrolyzed Sodium Hyaluronate

What Hydrolyzed Sodium Hyaluronate is & what it does

A very-low-molecular-weight hyaluronic acid fragment that absorbs quickly for deeper, longer-lasting hydration. It is frequently layered with larger forms for multi-depth moisture.

What is Hydrolyzed Sodium Hyaluronate and what does it do in sunscreen?

Hydrolyzed Sodium Hyaluronate is a very small, broken-down form of hyaluronic acid, a humectant that draws and holds water in the skin. Because the fragments are so small, they absorb quickly and reach a little deeper, giving longer-lasting hydration than larger forms. In a sunscreen it keeps the formula from feeling tight or drying and adds a smooth, hydrated finish.

Is Hydrolyzed Sodium Hyaluronate the same as hyaluronic acid?

It is a close relative. Hyaluronic acid, its salt sodium hyaluronate, and this hydrolyzed (broken-down) version are all part of the same family of humectants. The hydrolyzed form simply has a lower molecular weight, so it sinks in faster and is often layered with larger forms for hydration at more than one depth.

Is Hydrolyzed Sodium Hyaluronate safe?

Yes. Hyaluronic acid and its forms are among the best-tolerated, most widely used hydrating ingredients in skincare, suitable for sensitive and acne-prone skin. It mirrors a substance the skin and body already make, so it is non-irritating at cosmetic levels. Reactions are uncommon.

Does Hydrolyzed Sodium Hyaluronate clog pores?

No. It is a water-loving humectant rather than an oil or wax, so it is considered non-comedogenic. It is lightweight and absorbs quickly, which is why it is recommended even for breakout-prone skin. It will not block pores.

Is Hydrolyzed Sodium Hyaluronate vegan?

Usually. Most cosmetic hyaluronic acid today, including the hydrolyzed form, is produced by fermentation rather than from animal sources, which makes it suitable for vegan formulas. If this matters to you, check the brand's labeling, since sourcing can vary by manufacturer.
