Beta Arbutin

Beta Arbutin is a widely used skin-brightening cosmetic active ingredient known for helping to improve uneven skin tone, reduce the appearance of dark spots, and support a clearer, more radiant complexion. It works primarily by inhibiting tyrosinase activity, an enzyme involved in melanin production, thereby helping to control excess pigmentation.

Beta Arbutin is valued in cosmetic formulations for its water solubility, good stability, and gentler action compared to free hydroquinone when used within recommended limits.
