SODIUM ASCORBYL PHOSPHATE
Description
Sodium Ascorbyl Phosphate (SAP) is a stable, water-soluble derivative of Vitamin C that has gained significant attention in the skincare industry. This potent antioxidant offers numerous benefits for skin health and appearance, making it a valuable ingredient in various cosmetic formulations.
SAP functions as a powerful free radical scavenger, protecting skin cells from oxidative stress and environmental damage. Unlike pure ascorbic acid, SAP remains stable in aqueous solutions and at higher pH levels, ensuring longer shelf life and efficacy in skincare products. Upon absorption, it converts to ascorbic acid within the skin, delivering the benefits of Vitamin C effectively.
Key advantages of SAP include its ability to stimulate collagen synthesis, promote skin brightening by inhibiting melanin production, and provide anti-inflammatory effects. It has shown efficacy in treating acne due to its antibacterial properties and ability to reduce sebum oxidation. SAP is generally well-tolerated, even by sensitive skin types, making it a versatile option for various skincare needs.
Typical concentrations in skincare products range from 0.5% to 5%, depending on the formulation and intended benefits. SAP can be incorporated into serums, moisturizers, and other leave-on products for optimal results.
