Dioscorea Opposita (Wild Yam) Root Extract
What is Dioscorea Opposita (Wild Yam) Root Extract?
Dioscorea opposita root extract comes from the rhizome of the Dioscorea opposita plant, a perennial vine native to East Asia and widely cultivated for its edible tubers. In cosmetics, it belongs to the botanical extract category and serves primarily as a skin conditioning agent. The extract is rich in mucilage, polysaccharides, and glycoproteins, which form a protective film on the skin's surface. This helps retain moisture, enhance skin barrier function, and promote a supple texture. Typically incorporated into creams, lotions, and serums at low concentrations, it provides humectant-like effects without greasiness, supporting overall skin comfort in daily formulations.
