Vitamin C Serum
This serum uses Sodium Ascorbyl Phosphate (SAP), a stable derivative that lacks the robust clinical evidence for collagen synthesis associated with pure L-Ascorbic Acid. It fails the 'Duke Parameters' by omitting Ferulic Acid and utilizing a dropper bottle, which introduces oxygen and accelerates degradation of the active ingredients.
