| 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 US cosmetic-derm world's post-procedure gold standard. TNS — Tissue Nutrient Solution, a growth-factor complex derived from human fibroblast conditioned media — paired with signal peptides and barrier support. Clinical data on photoaging is published and serious. $295 is genuinely expensive, but the 4–6 week post-Fraxel case is exactly what this product was built for. |
