Sodium Ascorbyl Phosphate (SAP) is a water soluble and gentle form of Vitamin C that is known to be more stable for use in skincare than pure ascorbic acid. It is a combination of ascorbic acid, a phosphate and a salt and works as an antioxidant to protect and improve the skin’s environmental defense barrier.

Vitamin C within skincare is considered a pro-ageing superstar ingredient that everyone can use within their daily routine. It protects the skin’s barrier, reduces pigmentation to even skin tone and stimulates collagen production for firmer, plumper skin.

Pure ascorbic acid is highly acidic, unstable and can easily become oxidised when exposed to light and heat. Sodium Ascorbyl Phosphate is a derivative of ascorbic acid and is therefore less likely to become unstable. This is because it is made up of approximately 50% ascorbic acid and is stable up to a pH of 7. This makes it more gentle on the skin.

An added benefit of Sodium Ascorbyl Phosphate is that it treats acne-prone skin as it has an antimicrobial effect and reduces inflammation.
