AntioxidantBrightensCalms blemishes
A stable, gentle vitamin C derivative, antioxidant and brightening, with a reputation for suiting blemish-prone skin.
What it is
Sodium Ascorbyl Phosphate (SAP) is a water-soluble, stable derivative of vitamin C. It resists the oxidation that plagues pure ascorbic acid and converts to active vitamin C in the skin, delivering antioxidant and brightening benefits gently, with published interest in its suitability for blemish-prone skin.
How it works
Antioxidant defence
It neutralises free radicals from UV and pollution, protecting against the oxidative stress that dulls skin and drives pigment.
Brightens gently
It supports a more even, radiant tone over time, at a near-neutral pH that suits sensitive skin better than raw vitamin C.
The evidence
SAP is a well-regarded stable vitamin C derivative with good support for antioxidant protection, brightening, and gentleness, including specific interest for oily and blemish-prone skin.
Worth knowing
Different vitamin C derivatives suit different skin, SAP's strengths are stability and gentleness rather than raw potency.
