DropBrigt® SAP | Sodium Ascorbyl Phosphate

DropBright® SAP is a stable, water-soluble derivative of Vitamin C, specifically designed for enhanced stability and bioavailability. It functions as a potent antioxidant and skin-brightening agent, protecting the skin from free radicals, promoting collagen synthesis, and reducing melanin production. Compared to pure ascorbic acid, SAP offers superior stability against light, heat, and oxidation, making it ideal for advanced cosmetic formulations.

INCI Name: Sodium Ascorbyl Phosphate
CAS Number: 66170-10-3
Function: Whitening, Antioxidant, Anti-aging
EWG Score: 1 (Low Hazard)

Benefits

1. Whitening and Brightening:

   • Inhibits tyrosinase activity, reducing melanin synthesis and lightening dark spots.
   • Proven to promote a 90% reduction in melanin production at low concentrations.

2. Antioxidant Protection:

   • Scavenges free radicals, protecting the skin from oxidative stress and photoaging.
   • Enhances skin resilience and repair through powerful antioxidant activity.

3. Collagen Synthesis:

   • Promotes collagen production, improving skin elasticity and reducing wrinkles.

4. Gentle and Safe:

   • Suitable for sensitive skin due to its mild nature and stable formulation.

Suggested Usage
