Widely used in skincare products, this compound serves as a stable form of vitamin C. It helps brighten skin tone and reduce the appearance of dark spots by inhibiting melanin production. Commonly found in serums and moisturizers, it supports collagen synthesis, which can improve skin firmness and reduce fine lines. Its stability in the presence of heat and light makes it a preferred choice in formulations over other vitamin C derivatives. Also used in products targeting sun damage and uneven texture due to its antioxidant properties.
