Description

β-Arbutin

β-Arbutin is a highly effective and safe skin-lightening ingredient derived from natural bearberry plants or produced via advanced biotechnology. As a glycosylated derivative of hydroquinone, it selectively inhibits tyrosinase, the key enzyme responsible for melanin synthesis, thereby preventing the formation of dark spots, freckles, and uneven skin tone without affecting normal cell metabolism. This gentle yet potent action gradually brightens the complexion while maintaining skin health. In addition, β-Arbutin possesses strong antioxidant properties, which help neutralize free radicals and protect skin cells from oxidative stress, contributing to anti-aging effects and improved skin resilience. Widely incorporated into creams, serums, toners, masks, and other cosmetic formulations, β-Arbutin is favored for its versatility, efficacy, and compatibility with sensitive skin types. Its high purity, stability, and safety profile make it a top choice for modern skincare products seeking effective, reliable skin-brightening results.
