Verdict

The benchmark vitamin C serum the entire industry measures itself against. 15% L-ascorbic acid + 1% vitamin E + 0.5% ferulic acid — the Duke University antioxidant patent that spawned a thousand dupes. $182 is painful, but the 20-year clinical dataset on photoaging reversal is unmatched. Every derm office in America has a bottle on the shelf.

15% THD ascorbate — the stable, oil-soluble vitamin C. Glow without the sting.
