Description

What is Bearberry Extract Arbutin?

Bearberry is any one of a variety of low-profile bushes that grow to height of around 20 cm. The plant has a thick bark, and leathery oval leaves that are about 1.5 cm in length. The bark is usually covered in fine, silky hairs.

The flowers are either pink or white, and have five distinct petals, each one less than a cm in length. It grows a red fruit that is often confused with a relative, the American cranberry.

How Does Bearberry Extract Arbutin Work

Bearberry foliage, the part of the Arctostaphylos uva-ursi plant that is most commonly used in cosmetic formulations, has been shown to effectively scavenge free radicals, unstable molecules that contribute to the formation of premature wrinkles and fine lines on the skin. Indeed, a study published in the March 2004 issue of the journal Food Chemistry found that bearberry leaf extract had even stronger free radical scavenging (i.e. antioxidant) properties than extracts made from wild licorice (Glycyrrhiza lepidota), senega (Polygala senega), narrow-leaved echinacea (Echinacea angustifolia), and aerial parts of two varieties of horsetail (Equisetum spp.). The researchers also pointed out that the polyphenolic compounds found in bearberry leaves appeared to be responsible, at least in part, for bearberry extract’s antioxidant capacity.

But the extraordinary antioxidant properties of bearberry extract is not what Dr. Oz’s anti-aging guide for 2014 highlighted. Turns out, the leaves of the Common Bearberry also contain arbutin, a natural compound that has been shown to inactivate tyrosinase, an enzyme that is responsible for skin pigmentation. In the skin, tyrosinase converts the amino acid tyrosine into melanin, a natural substance that gives your skin its color. Melanin also determines the color of your hair and eyes.

Hyperpigmentation occurs when the melanin-producing cells at the lower layer of the epidermis produce too much melanin which then forms deposits in the skin. This annoying, but not necessarily dangerous skin disorder can be caused by things like sun damage or other skin injuries, inflammation, or acne vulgaris. People with darker skin tones are more likely to suffer from hyperpigmentation, especially if they have had excessive exposure to the sun’s UV rays

Due to its role as a tyrosinase inhibitor, arbutin has become a common ingredient in skin-whitening products designed to treat age spots, freckles, melasma, and other hyperpigmentation problems. In addition to bearberry leaf extract, common tyrosinase inhibitors include mulberry, blueberry leaves, cranberry leaves, licorice extract, vitamin C, kojic acid, and burnet root extract.
