α-Arbutin is widely used in the cosmetics and skincare industry as a skin-lightening agent. It helps reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone by inhibiting the activity of tyrosinase, an enzyme involved in melanin production. Its gentle nature makes it suitable for sensitive skin types, offering a safer alternative to harsher brightening agents like hydroquinone. Additionally, α-Arbutin is incorporated into anti-aging products to improve skin radiance and texture. It is often found in serums, creams, and lotions designed to promote a more even and youthful complexion.
