Arctostaphylos Uva Ursi (Bearberry) Extract is a plant-derived ingredient containing arbutin, a naturally occurring compound that inhibits tyrosinase activity to reduce melanin production. It is used in topical formulations to help even skin tone and address hyperpigmentation, and also provides antioxidant benefits.
