#139) Which Vitamin C (Ascorbic Acid) Serum is Better? Water or Anhydrous?

Vitamin C, ascorbic acid, is famously known as the only rigorously tested antioxidant for age prevention. Yet this active is also notoriously known for its quirky characteristics in the classic CE Ferulic serum format. This unstable hot dog water has often generated concerns for using it long term. In this episode, the chemists discuss ascorbic acid’s stability and compare vitamin C in water-based formulas vs. anhydrous formulas to see if there’s a better format for this finicky active.
