1. CLEANSE & TONE.
2. PREVENT WITH SERUM 10.
Formulated with AOX+ advanced antioxidant technology, this lightweight, fast-absorbing serum combines ferulic acid with 10% pure vitamin C to enhance antioxidant performance.
L-ascorbic acid has a reservoir effect, which means it can't be washed off or rubbed off for a minimum of 72 hours.
The addition of ferulic acid stabilizes and enhances the absorption of vitamin C.
