  • A skin identical anti-aging peptide, which stimulates collagen synthesis and supports skin volume and elasticity
  • Anti-glycation active that also acts against damages induced by InfraRed radiation

Sodium Potassium Aluminium Silicate

  • Ceramic microspheres coated in SiO2 and TiO2, which provides a physical shield that protects skin from pollution
  • The unique shape of the substrate and the sophisticated coating technology also
    provide simultaneous light diffusing and mattifying properties

    skin to convert to relevant metabolites as required
  • Stimulates connective tissue production to retain firmness and elasticity
  • Controls abnormal melanin production within the skin
  • Smooths skin texture and encourages radiance by increasing cell turnover to a
    healthy rate

Vitamin C Complex (Ascorbyl Tetraisopalmitate + Sodium Ascorbyl Phosphate)
