What Is Wild Yam Root Extract?
Wild yam root extract is derived from Dioscorea villosa, a plant native to North America. It contains diosgenin, a plant steroid that serves as a precursor to hormones and has phytoestrogenic properties.
While diosgenin cannot be converted to hormones in the human body, topical application may still provide benefits for hormonally-influenced skin conditions. The extract is soothing and helps support skin during hormonal fluctuations.
Wild yam is often used in products targeting menopausal skin or skin affected by hormonal changes.
