The Receipt
- 01Gentle and plausible; the receipt is mostly small and manufacturer-led. Sunscreen and retinoids still come first.
Education, not a diagnosis. If something changes quickly, hurts, bleeds, or worries you, see a dermatologist.

INCI: Palmitoyl Pentapeptide-4, Acetyl Hexapeptide-8, Copper Tripeptide-1 (and many others)
Peptide serums promise firmer skin. A plain-English look at signal, carrier and “Botox-like” peptides, and how thin the evidence still is.

Peptides are short chains of amino acids. Skincare peptides are marketed as messengers that tell skin to make collagen.
Peptides are grouped roughly as signal peptides (said to stimulate collagen), carrier peptides (e.g. copper peptides), and neurotransmitter-inhibiting peptides (marketed as topical “Botox”).
A review of topical peptides found some promising small studies but noted most were short, small and often funded by manufacturers. Whether peptides penetrate well enough to act as claimed is still debated.
““Botox in a bottle” peptides relax wrinkles like injections.”
Topical peptides haven’t been shown to work like neurotoxin injections.
