White licorice extract (often Dipotassium Glycyrrhizate or high-purity Glycyrrhiza glabra) is a potent, water-soluble cosmetic ingredient used for skin lightening, anti-inflammation, and soothing. It inhibits tyrosinase to reduce melanin production, fading dark spots, acne scars, and hyperpigmentation. It is commonly used in serums and creams at 0.1–3.5% concentrations.
