23-Hydroxyursolic acid is a triterpenoid compound used in skincare formulations for its anti-inflammatory and antioxidant properties, helping to soothe irritated skin and reduce signs of aging. It is also investigated for promoting hair growth by supporting follicle health. In dietary supplements, it shows promise for metabolic support, including glucose regulation, lipid metabolism, and blood sugar lowering. Research highlights its antimicrobial activity against certain bacteria, potential in immune modulation, and role in cancer prevention by inducing apoptosis in abnormal cells and inhibiting angiogenesis in tumors such as liver and colon cancer. Commonly found in natural product extracts, it is of interest for cosmetic, nutraceutical, and pharmaceutical applications targeting chronic conditions like diabetes, inflammation, and cancer. Further studies are needed to confirm efficacy and safety in humans.
