Ulmus Fulva (Slippery Elm) Bark Extract
What is Ulmus Fulva (Slippery Elm) Bark Extract?
Ulmus Fulva Bark Extract is derived from the inner bark of the slippery elm tree (Ulmus rubra, formerly Ulmus fulva), a deciduous species native to eastern North America. This botanical ingredient is characterized by its high mucilage content, primarily polysaccharides like galactoarabinoxylans, which swell in water to form a viscous, gel-like substance. In cosmetic products, it functions as a skin conditioning agent, typically incorporated into creams, lotions, and serums at low concentrations. Its mechanism involves creating a breathable film on the skin surface that attracts moisture from the environment and formulation, while also occluding to prevent transepidermal water loss. This emollient-humectant action contributes to softer, more supple skin texture without greasiness, leveraging its traditional demulcent qualities for gentle surface protection.
