Bearberry Brown Liquid Extract — Arctostaphylos uva-ursi — Cosmetic Grade
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.
Key Benefits
-
Tyrosinase inhibition & brightening — arbutin is a clinically validated tyrosinase inhibitor; reduces melanin synthesis and targets dark spots, uneven skin tone, and post-inflammatory hyperpigmentation (PIH)
-
Hyperpigmentation support — one of the most effective natural alternatives to hydroquinone; suitable for brightening serums, spot treatments, and complexion-evening formulations
-
Antioxidant protection — tannins and flavonoids neutralize free radicals and reduce oxidative stress-driven skin aging
-
Anti-inflammatory & soothing — reduces pro-inflammatory mediators; calms redness and irritation in sensitive and reactive skin
-
Antimicrobial activity — tannins contribute to antimicrobial properties; supports acne-prone skin formulations
-
Synergistic brightening — pairs exceptionally well with Vitamin C, Niacinamide, and other tyrosinase inhibitors for enhanced brightening efficacy
How to Use
-
Incorporation: Add directly to the water phase or at cool-down (below 40°C) to preserve heat-sensitive arbutin and flavonoids
-
Recommended Usage Rate: 1–10% in finished formulations (2–5% most common for brightening serums and toners)
-
Solubility: Water-soluble; incorporate in the water phase
-
Processing temperature: Add at cool-down (below 40°C) preferred; avoid prolonged high heat
-
pH & shelf life: Refer to your supplier's Certificate of Analysis (CoA) or Technical Data Sheet (TDS) for confirmed values
