| 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. | Deciem's flagship peptide serum and the successor to the discontinued Buffet + Copper Peptides 1% — eight peptides in one bottle plus copper tripeptide-1 (GHK-Cu) at the high #4 placement, which is the slot that earns the bottle its blue tint and the price tag. The peptide line-up is the most credible single-bottle stack on the market at this price tier: copper tripeptide-1 for tissue repair and signaling, acetyl hexapeptide-8 (the 'Botox-mimic' Argireline) for expression-line softening, pentapeptide-18 for similar muscle-relaxant signaling, palmitoyl tripeptide-1/-38 + tetrapeptide-7 (the Matrixyl 3000 family) for collagen-and-elastin upregulation, plus dipeptide diaminobutyroyl benzylamide diacetate (Syn-Ake) and the ARG-TRP-DIPHENYLGLYCINE peptide (anti-fatigue) rounding it out. The amino acid + sugar NMF blend in the second half of the deck mimics the skin's own moisture factors. Use cases: AM or PM, layered as the treatment step under moisturizer; pairs cleanly with vitamin C in AM (peptides survive C just fine despite older internet folklore). The watery vehicle stays compatible with retinoids in PM. At $32 / 30ml it's the cheapest credible 8-peptide stack in skincare — adjacent prestige multi-peptide serums (Drunk Elephant Protini, Niod CAIS) sit at 3-4x. |
