Why This Ingredient Matters
Ascorbic Acid is the pure, biologically active form of Vitamin C and one of skincare’s most extensively researched antioxidants. It helps improve visible brightness, tone, texture, and signs of aging while providing antioxidant support.
Why Formulation Matters
Pure Vitamin C is highly effective but can be difficult to formulate because its stability and performance depend heavily on concentration, pH, and the ingredients surrounding it.
Luzern formulates V15+ with 15% Ascorbic Acid at an optimized pH of 3.2.
