Retinol, with the chemical formula C20H30O, is a lipophilic (fat-soluble) compound susceptible to oxidation, converting into less active forms such as retinal or retinoic acid, and can degrade into its active acidic form when exposed to heat or light. It offers significant functional benefits, including anti-aging properties by promoting cell turnover to reduce fine lines and wrinkles, acne treatment through sebum regulation and exfoliation, reduction of hyperpigmentation and sunspots by stimulating collagen and elastin, and improvement of skin texture by smoothing rough areas. As an essential nutrient, retinol supports vision (especially night vision), immune function, and cell growth, and also acts as an antioxidant in certain systems. Its uses span cosmetics, such as anti-aging creams and acne treatments, dietary supplements for eye, skin, and immune health, and pharmaceutical applications in retinoid-based prescription drugs for skin conditions.
