Key Ingredients

  • Ascorbic Acid (L): A powerful antioxidant that protects the skin against DNA mutations, neutralizes free radicals and increases cell immunity; signals collagen production, increases elasticity and decreases fine lines and wrinkles. An important antioxidant to use in conjunction with sunscreen for additional protection against skin aging.
  • Palmitoyl Tripeptide:  Known as the peptide SYN-COLL and referred to as synthetic collagen, this powerful peptide mimics the body’s mechanism to produce collagen. A clinical study demonstrated an increase in collagen synthesis by 119%.
  • Magnesium Ascorbyl Phosphate: A non-irritating, more stable form of vitamin C. This form is equally as effective in collagen synthesis by acting as a telomerase inhibitor, increasing the healthy lifespan of skin cells. It also has the same properties as L-ascorbic acid regarding cell immunity, antioxidant protection and lightening properties.
