Sodium Ascorbyl Phosphate
Sodium Ascorbyl Phosphate is a stable, water-soluble form of vitamin C commonly used in UK skincare products. It is gentler than pure ascorbic acid, making it suitable for sensitive skin while still delivering antioxidant protection and brightening effects. Shoppers often choose it for its ability to help even skin tone without irritation.
How it works in skincare
In cosmetics and skincare, Sodium Ascorbyl Phosphate functions as a potent antioxidant that helps neutralise free radicals generated by UV exposure and pollution. It converts to ascorbic acid within the skin, supporting a brighter, more even complexion and aiding the appearance of firmness. Formulators favour it for its excellent stability in water-based serums, creams and masks, allowing effective delivery without the oxidation issues common to pure vitamin C.
