About this ingredient
Arctostaphylos Uva-Ursi Leaf Extract (bearberry leaf extract) is a plant source of arbutin, a precursor that releases hydroquinone very slowly. In a formula it is used to even out tone and soften pigment spots. Its mechanism is plausible: arbutin partly inhibits tyrosinase, the key enzyme of melanin synthesis. Still, clinical evidence for the whole extract is modest and depends heavily on the arbutin concentration. It makes sense to treat it as a supporting component in a brightening routine alongside sun protection, not as a strong bleaching agent. Topically the systemic contribution is negligible, so it can be applied during pregnancy and breastfeeding. Tolerance is good: low irritation and allergy potential, suitable for sensitive skin. As with any tone active, pair it with sunscreen or the result fades.
