BearBerry aqueous extract

Description

Bearberry (aqueous extract)

Bearberry aqueous extract is a high-potency botanical ingredient derived from the leaves of Arctostaphylos uva-ursi. This 1;2 product-to-solvent ratio ensures a concentrated delivery of Arbutin, a natural hydroquinone derivative renowned for its skin-brightening efficacy without the typical irritation associated with synthetic lighteners.

Botanical & INCI Information

Scientific Name: Arctostaphylos uva-ursi (L.) Spreng.
INCI Name: Arctostaphylos Uva-Ursi Leaf Extract (and) Aqua.

Key Cosmetic Benefits

Skin Brightening & Depigmentation: The primary active, alpha-arbutin, inhibits tyrosinase activity, reducing melanin production to fade dark spots, hyperpigmentation, and “age spots.”
Antioxidant Protection: Rich in tannins (allantoin) and flavonoids, it neutralizes free radicals and protects the skin from oxidative stress induced by UV exposure.
Astringent & Purifying: Natural tannins provide a mild pore-tightening effect, making it suitable for oily or blemish-prone skin types.
Anti-Inflammatory: Helps soothe minor skin irritations and even out skin tone.

Formulation Guidelines

Solubility: Fully water-soluble; ideal for serums, toners, and the water phase of creams.
Usage Levels: Recommended at 1% to 5% for standard brightening formulations.
Stability: Highly sensitive to oxidation; it is best formulated at a pH of 4.0–6.0 to ensure arbutin stability.
Temperature: Should be added during the cooling phase (below 40°C) to prevent degradation of heat-sensitive glycosides.
Synergy: Frequently paired with Vitamin C or AHAs for enhanced radiance
