Features
SP-VC, or Phytosphingosine Ascorbate, is a vitamin C derivative formed by combining phytosphingosine—one of the sphingolipid components that make up the skin’s protective barrier—with ascorbic acid (vitamin C).
Key Features
- Phytosphingosine has excellent antibacterial properties and promotes ceramide synthesis, helping to strengthen the skin barrier, improve hydration, and support skin regeneration, elasticity, and wrinkle reduction.
- Vitamin C provides strong antioxidant effects and inhibits melanin production, resulting in skin brightening and tone improvement.
- • SP-VC combines the benefits of both components in a stable form as a complex active ingredient.
