Bearberry (Arctostaphylos uva-ursi) is one of the most potent and well-researched botanical brightening actives in modern cosmetic science. Its primary bioactive compound, arbutin — a naturally occurring glycoside of hydroquinone — is a gold-standard tyrosinase inhibitor widely used in professional brightening and hyperpigmentation formulations. This brown liquid extract delivers the key bioactive compounds of Arctostaphylos uva-ursi — including arbutin, hydroquinone (trace), tannins, and flavonoids — in a ready-to-use, water-soluble form for direct incorporation into the water phase of brightening serums, toners, spot treatments, and complexion-evening formulations.
Professional cosmetic ingredient — not a finished product.

I formulated a beautiful Mangosteen & Astaxanthin glaze with it! Perfect addition, and gentle enough for sensitive skin.
A hard to find, specialty ingredient that adds natural silkiness to any formulation!
Good Material. I used it for my Skin Care Formulation, and blends well with other materials.
Great
Using this in my DIY oil-based lotion to make it less greasy and it really does do the job intended for! Happy with the purchase
