Sodium Ascorbyl Phosphate (SAP)
Stable Vitamin C Derivative for Brighter, Healthier Skin
What Is Sodium Ascorbyl Phosphate (SAP)?
SAP is a water-soluble, stabilized form of Vitamin C (ascorbic acid). It’s synthesized to overcome the instability and oxidation issues of pure L-ascorbic acid, making it ideal for skincare formulations. Once applied, enzymes in the skin convert SAP into active ascorbic acid, delivering Vitamin C’s benefits without irritation.

✨ Collagen Boost: Stimulates collagen synthesis for firmer, plumper skin.
✨ Acne Control: Exhibits antibacterial properties, targeting C. acnes bacteria and reducing breakouts.
✨ Gentle & Stable: Less acidic than L-ascorbic acid, making it suitable for sensitive or reactive skin.
