Sodium Ascorbyl Phosphate (SAP) is a highly stable and water-soluble vitamin C derivative that has become a cornerstone ingredient in advanced skincare and personal care formulations. This innovative antioxidant compound delivers exceptional skin-brightening and anti-aging benefits while maintaining remarkable stability in cosmetic products. As a next-generation vitamin C precursor, SAP gradually converts to active L-ascorbic acid in the skin, providing sustained antioxidant protection and collagen synthesis stimulation.
