Centella Asiatica (Cica) extract is a plant-derived ingredient rich in triterpenoids such as asiaticoside, madecassoside, asiatic acid, and madecassic acid, used in skincare for its soothing, anti-inflammatory, antioxidant, and wound-healing/barrier-supporting properties. It is commonly included in formulations aimed at calming sensitive, irritated, or compromised skin.
