Latin- Arctostaphylos uva-ursi, Bearberry also known as Uva-Ursi is a leaf extract with cleansing and skin-brightening (lightening) properties. It is well known in folklore to act as a skin-whitening agent. Cosmetic scientists have prepared an extract of the plant and demonstrated how this whitening happens. The properties of the plant have demonstrated an effect inhibiting melanin production in human melanocytes by reducing tyrosinase (enzyme) activity. This means the skin becomes lighter as melanin is the pigment that darkens skin; therefore a reduction in melanin results in a reduction of skin pigment, and thus lighter skin. It has been demonstrated to be a better whitener than kojic acid or L-ascorbic acid, and has also been demonstrated to be more effective as an antioxidant than hydroquinone.
