Best Vitamin C Serum Dermatologist

C E Ferulic

The clinical reference standard against which every other vitamin C serum is measured. C E Ferulic combines 15% L-ascorbic acid, 1% vitamin E, and 0.5% ferulic acid in a patent-backed formulation that delivers meaningful photoprotection and long-term skin improvement. The $182 price is painful, and dupes exist that get close, but nothing else has quite the same clinical pedigree.
