Science
Mechanism of Action
PATP operates as a powerful antioxidant by neutralizing free radicals, thereby protecting skin structures like collagen and elastin from oxidative damage and preventing visible signs of aging. The vitamin C component actively brightens the complexion and mitigates hyperpigmentation by inhibiting melanin synthesis. Concurrently, the vitamin E element provides critical lipid protection, stabilizes cellular membranes, and enhances the skin's moisture retention. Additionally, PATP stimulates collagen production for improved firmness and elasticity, while also offering anti-inflammatory and skin conditioning benefits.

Key findings
- 01 Cosmetic formulations typically use Potassium Ascorbyl Tocopheryl Phosphate within a 0.5% to 3% concentration range, which is effective for delivering antioxidant benefits across all skin types, including sensitive skin, without inducing irritation.
- 02 Studies on Sodium Ascorbyl Phosphate (SAP), a similar stable vitamin C derivative, demonstrated a reduction in wrinkle depth and enhanced skin elasticity in human volunteers when incorporated at 5% in emulgel preparations.
