Sodium Ascorbyl Phosphate
What is it?
Sodium Ascorbyl Phosphate is a stable, water-soluble vitamin C ester derivative, used in skincare as a gentler alternative to L-ascorbic acid with better formulation stability.
What does it do?
Commonly used as a stabilized vitamin C derivative for antioxidant and brightening benefits with fewer stability/irritation concerns than pure L-ascorbic acid. A systematic review of vitamin C in dermatology confirms stabilized derivative systems consistently improve photoaging and pigmentary disorders, and a related vitamin C ester derivative (magnesium ascorbyl phosphate) has been shown to provide real antioxidant photoprotection when combined with mineral UV filters.
