Product Description:

Magnesium L-ascorbate phosphate, also known as magnesium ascorbyl phosphate, is a stable, water-soluble derivative of vitamin C (L-ascorbic acid). It is formed by esterifying the 2-position hydroxyl group of ascorbic acid with a phosphate group and subsequently forming a magnesium salt. This chemical modification significantly enhances its stability against oxidation, heat, and light compared to pure ascorbic acid, making it suitable for incorporation into various formulations. Its primary application is in the cosmetic and personal care industry as a highly effective skin-brightening and anti-aging active ingredient. Upon topical application, it is enzymatically hydrolyzed by phosphatases in the skin to release active L-ascorbic acid. It functions by inhibiting tyrosinase activity, thereby reducing melanin synthesis and helping to fade hyperpigmentation and dark spots. Furthermore, as a precursor to vitamin C, it promotes collagen synthesis, provides antioxidant protection against free radicals generated by UV exposure, and aids in skin repair. In the pharmaceutical sector, it is utilized as a novel and functional excipient, particularly in advanced topical and transdermal drug delivery systems. Its role extends beyond a simple stabilizer; it can act as a penetration enhancer and a source of bioactive vitamin C in medicated creams or patches designed for wound healing, scar reduction, or dermatological treatments. Its excellent stability profile allows for longer shelf life of finished products containing this active form of vitamin C.
