Lepidium Meyenii (maca) root extract is a botanical ingredient rich in polyphenols, glucosinolates, and amino acids, used in skincare for its antioxidant and conditioning properties. It is sometimes marketed for soothing, energizing, or revitalizing effects, though robust clinical dermatological evidence is limited.
