β-Arbutin is a naturally occurring hydroquinone glycoside found in the leaves of bearberry (Arctostaphylos uva-ursi), as well as in blueberry, cranberry, and pear. It is produced via enzymatic synthesis or plant extraction, yielding a high-purity, water-soluble active ideal for cosmetic and pharmaceutical applications.
As a reversible inhibitor of tyrosinase, β-Arbutin is widely used in skin-brightening formulations, hyperpigmentation treatments, and as a stabilizer in color-sensitive products. Its gentle profile and compatibility with other actives make it a preferred choice for premium skincare brands and dermatological preparations.
