Sodium Ascorbyl Phosphate

Sodium Ascorbyl Phosphate (SAP) is a stable, water-soluble derivative of Vitamin C known for its powerful antioxidant, brightening, and anti-acne benefits. It protects the skin from oxidative stress, supports collagen synthesis, and helps fade dark spots for a radiant, even complexion. Compared to pure Vitamin C (L-Ascorbic Acid), SAP offers excellent stability and is gentle enough for all skin types, including sensitive and acne-prone skin.
