Bearberry extract is obtained from the leaves of Arctostaphylos uva-ursi through aqueous-ethanol extraction. The primary bioactive compound is arbutin (hydroquinone-beta-D-glucopyranoside), along with tannins, flavonoids, and phenolic acids.
Arbutin inhibits tyrosinase activity, making bearberry extract a sought-after ingredient for skin-brightening applications. The extract also demonstrates antimicrobial and diuretic properties beneficial for urinary tract health. It is commercially used in cosmetic skin-lightening formulations, urinary health supplements, and dermatological products.
