Product Description:
Sodium Ascorbyl Phosphate (SAP) is a highly stable, water-soluble derivative of Vitamin C known for its excellent antioxidant, brightening, and anti-acne benefits. Compared to pure ascorbic acid, SAP maintains its potency much longer and is gentle on the skin, making it ideal for sensitive or acne-prone skin types.
It helps even out skin tone, reduce hyperpigmentation, boost collagen production, and protect the skin from environmental stressors. SAP also exhibits antimicrobial activity against acne-causing bacteria C. acnes, making it a popular choice for brightening and clarifying skincare formulations such as serums, creams, toners, and gels.
