Cimicifuga Racemosa (black cohosh) root extract is a plant-derived ingredient containing triterpene glycosides, isoflavones, and phenolic compounds, used in skincare for antioxidant and skin-conditioning effects, sometimes promoted for phytoestrogenic or soothing properties. Topical efficacy data are limited compared with its better-studied oral use.
