Sodium Ascorbyl Phosphate (SAP)

Description

Sodium Ascorbyl Phosphate (SAP) is a gentle, stable form of Vitamin C ideal for brightening, protecting, and improving overall skin texture. Unlike pure ascorbic acid, SAP is less irritating, more pH-stable, and suitable for sensitive skin. It helps to fade dark spots, reduce the appearance of acne, and supports collagen production, making it excellent for anti-aging and brightening skincare.

INCI Name: Sodium Ascorbyl Phosphate

💡 SAP is especially good in water-based serums and creams where pure Vitamin C would degrade quickly.
