The detail
What you need to know
How it works
Twelve peptides, four roles
Everything the original Liquid Peptides fields, Matrixyl-family signal peptides (palmitoyl tripeptides 1, 5 and 38, tetrapeptides 7 and 21), the Argireline-and-pentapeptide-18 expression pair, the copper carrier heptapeptide and carnosine on guard, plus an expanded bench: palmitoyl tetrapeptide-10, a larger renewal oligopeptide and an arginine/lysine polypeptide extending the signalling repertoire.
Peptides high in the deck
Palmitoyl tripeptide-38 sits fifteenth of sixty with the rest clustered close behind, unusually forward placement for peptide chemistry, and the honest difference the price buys alongside the wider roster.
The texture upgrade
A light silicone-cushioned emulsion rather than a water serum: it carries the lipophilic peptide esters comfortably and doubles as a soft primer under moisturiser. Hyaluronic acid, panthenol and prebiotic inulin do the hydration; vitamin E guards the emulsion. The lactic/glycolic entry is a film-forming copolymer, not an acid.
The honest frame, unchanged
More voices, same diplomacy: peptides persuade over eight to twelve weeks at zero irritation cost, they do not perform surgery.
How to use
Morning and/or evening on clean skin: 3–4 drops massaged over face and neck before moisturiser.
Plays without conflict alongside every active on the shelf.
Who it suits
Committed peptide users graduating from Liquid Peptides, retinoid-free ageing routines wanting the fullest peptide bench available, including through pregnancy and breastfeeding, and mature skin preferring a cushioned serum-emulsion texture.
Worth knowing
Contains sodium metabisulfite, avoid with a known sulfite sensitivity. Fragrance-free and acid-free otherwise, and as low-conflict as its sibling.
The advanced seat of the peptide chair, choose it or Liquid Peptides, not both; the pair mirror the C-Tetra ladder logic of picking your tier. Daytime firming partner to a Crystal Retinal night, over Hydr8 B5 if layering (thinnest first), under any moisturiser. One peptide leader per routine remains plenty.
