Sodium ascorbyl phosphate is a highly stable form of vitamin C that has been chemically stabilised with salt. This stabilisation enables for easy penetration into the skins lipid barrier, where, once absorbed, it quickly converts into ascorbic acid, the pure form of vitamin C. This quick absorption means sodium ascorbyl phosphate is less irritating than other forms of vitamin C and is suitable for those with sensitive skin. This stabilisation also means that the benefits of the vitamin C remain potent and effective throughout the use of the product. This is a key advantage over pure vitamin C, which is known to quickly oxidise and degrade upon external exposure. Sodium ascorbyl phosphate has powerful antioxidant benefits that fight signs of ageing, preventing the appearance of fine lines and wrinkles by stimulating the production of collagen and protecting against environmental aggressors. It also helps diminish discolouration and age spots by inhibiting the production of melanin, resulting in an even, brighter complexion. A unique benefit of sodium ascorbyl phosphate compared to alternative forms of vitamin C is that it can be used as an effective acne treatment. As well as having antimicrobial properties, it reduces sebum oxidation (the process whereby oil on the surface of the skin reacts with oxygen) which results in clogged pores and encourages the formation of blackheads. By inhibiting this process, skin imperfections are reduced.
