Retinyl Palmitate(CAT: A000488) is the ester form of vitamin A (retinol) combined with palmitic acid, widely used in cosmetics, nutraceuticals, and pharmaceuticals for its skin-restoring and antioxidant properties. It serves as a stable precursor to retinol, gradually converting into active vitamin A within the skin or body. Commonly found in anti-aging formulations, sunscreens, and moisturizers, retinyl palmitate promotes cell turnover, improves skin tone, and supports collagen synthesis. In nutritional supplements, it functions as a pro-vitamin A source, essential for vision, immune health, and cellular growth. Its improved stability over free retinol makes it ideal for long-shelf-life formulations.
