Arbutin

Description

Arbutin is a naturally occurring compound found in various plant sources, including bearberry, cranberry, and pear trees. It is widely recognized in skincare for its skin-brightening and hyperpigmentation-reducing properties. Chemically, arbutin is a hydroquinone glycoside that works by inhibiting tyrosinase, the enzyme responsible for melanin production.

This ingredient exists in two forms: alpha-arbutin and beta-arbutin. Alpha-arbutin is considered more potent and stable than its beta counterpart. Arbutin's effectiveness in treating dark spots, melasma, and uneven skin tone has made it a popular alternative to hydroquinone, particularly due to its milder nature and fewer side effects.

Typically used in concentrations between 1% and 2%, arbutin can be found in various skincare formulations, including serums, creams, and toners. It is generally well-tolerated by most skin types and can be used in conjunction with other brightening agents like vitamin C and niacinamide. Regular use of arbutin-containing products may result in visible improvements in skin tone within 4-8 weeks, with continued benefits over time.
