Used primarily in skincare and cosmetic formulations, this ingredient serves as a stable, oil-soluble form of vitamin C. It penetrates the skin more effectively than many water-soluble vitamin C derivatives, delivering antioxidant benefits deep into the dermal layers. It helps reduce the appearance of fine lines, brighten skin tone, and support collagen production. Commonly found in anti-aging creams, serums, and sunscreens, it provides photoprotection by neutralizing free radicals caused by UV exposure. Its stability in formulations makes it ideal for products that require long shelf life without losing efficacy. Also used in products designed for oily or acne-prone skin due to its non-irritating and non-comedogenic properties.
