The Messengers
Peptides
Short amino acid chains that signal younger-looking skin behaviour.
What it is
In plain language
Peptides are short chains of amino acids — the building blocks of proteins like collagen, elastin and keratin. Applied topically, they act as cell-signalling molecules that encourage the skin to behave as if younger.
The science
How it actually works
Signal peptides (e.g. Matrixyl 3000, Palmitoyl Tripeptide-1) stimulate fibroblasts to produce more collagen. Carrier peptides deliver trace elements essential for repair. Neuropeptides (e.g. Argireline) relax expression-line micro-movements at the surface of the skin.
