α-Arbutin

CAS No.: 84380-01-8

What’s the α-Arbutin?

Alpha Arbutin, or α-Arbutin, is a glycosylated hydroquinone, and an anomer of the naturally occurring arbutin. Cosmetic and pharmaceutical industries usually use it for its skin lightening effects, treatment of hyperpigmentation, and as a safer alternative to hydroquinone.

How it works?
Its mechanism of action on skin isn’t fully understood; however, it’s believed to work by interrupting or limiting the ability of an enzyme in skin (known as tyrosinase) from making too much melanin. This in turn helps reduce the size and appearance of surface discolorations. As an antioxidant, alpha-arbutin can help neutralize skin-damaging free radicals, and also help boost skin’s natural antioxidant defenses.

What’s it Benefits

Alpha arbutin is a popular skincare ingredient to target hyperpigmentation, because it’s powerful but gentle skin-lightening properties. Here’s a detailed look at the benefits of alpha arbutin.
1. Skin Brightening
It inhibits the enzyme tyrosinase, responsible for melanin production. This helps in reducing hyperpigmentation including melasma and age spots. It leaves the skin looking brighter and more even toned.
2. Gentle on the Skin
It is known for its gentle action on the skin. Its slow release into the skin reduces the risk of irritation. This makes it better for more sensitive skin.
3. Works Well With Other Skincare Products
You can use alpha arbutin alongside other active skincare ingredients like Vitamin C, exfoliating acids and retinoids. This flexibility allows it to be part of a comprehensive skincare routine to target multiple skin concerns.
4. Safe for Regular Use
Compared to other brightening agents, it is less aggressive, thus it’s typically safe to use in the long-term.
