Our take
Is Sodium Dextran Sulfate a Good Ingredient?
It rates Fair: it provides film-forming slip and a hydrated feel, but strong evidence for unique, long-term skin benefits is limited. Some users may experience transient tightness or mild irritation, especially around the eyes.

It's used in hydrating serums, essences, eye gels, and sheet masks to boost slip and a soft finish, and appears in gel moisturizers to help stabilize texture.
Before you use it
Safety
It's typically low irritation at cosmetic use levels, but the sulfated polymer can occasionally feel tacky or cause minor stinging on compromised or delicate skin. Avoid direct contact with eyes if sensitivity occurs.
