| Verdict | Dermalogica's vitamin C serum uses ascorbyl glucoside — a stable derivative that converts to L-ascorbic acid in the skin, avoiding the oxidation problem that plagues pure vitamin C serums. A palmitoyl tripeptide boosts collagen signalling, lactic acid provides gentle exfoliation, and the brand's proprietary longevity complex adds adaptive defence. The professional skincare brand that trained a generation of aestheticians applies that clinical seriousness to an ingredient category crowded with unstable, overpriced options. | 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. |
