SAP (Sodium Ascorbyl Phosphate)

Sodium Ascorbyl Phosphate (SAP) is a highly stable, water-soluble derivative of Vitamin C (ascorbic acid) widely used in skincare for its antioxidant, brightening, and anti-aging properties. It acts as a gentle, non-irritating alternative to pure Vitamin C, converting into active Vitamin C upon skin contact.

Key Details About SAP:

Synonyms/Related Forms: Vitamin C derivative, Ascorbic acid salt.

Benefits: It neutralizes free radicals, boosts collagen synthesis to reduce wrinkles, fades hyperpigmentation/dark spots, and provides anti-inflammatory effects.

Acne Treatment: Notably, a 5% concentration is proven effective against acne vulgaris, reducing bacteria and controlling acne-causing oil oxidation.

Usage/Formulation: It is used in serums, lotions, and creams (commonly 0.2-3% concentration) and remains stable at a higher, less acidic pH (around 6-7) compared to L-ascorbic acid.
