Arbutin is a naturally occurring compound found in various plants, including bearberry, blueberry, and cranberry. It is known for its skin-brightening properties and is often used in cosmetic products to help reduce the appearance of dark spots and uneven skin tone. Arbutin works by inhibiting the enzyme tyrosinase, which plays a key role in melanin production. In addition to its skin-lightening effects, arbutin is also valued for its antioxidant properties. This means it can help protect the skin from damage caused by free radicals, which are unstable molecules that can lead to premature aging. As a result, arbutin is a popular ingredient in many skincare formulations aimed at promoting a healthier complexion.
