Four peptide families, four jobs
Treat peptide selection as job-to-be-done, not ingredient-deck shopping. The four families we work with each do different work in the skin.
- Signal peptides (e.g. palmitoyl tripeptides) — tell skin to make more collagen
- Carrier peptides (e.g. copper tripeptide-1) — deliver trace elements to repair sites
- Enzyme-inhibitor peptides (e.g. tetrapeptides) — slow down breakdown of existing structure
- Neurotransmitter-inhibitor peptides (e.g. acetyl hexapeptide-8) — reduce expression-line contraction
Dose at the published clinical level — or don't claim it
The biggest claim risk we see is brands name-checking a peptide on the deck while dosing it at a tenth of the level the published clinical study used. Either dose at the study level (and pay for the active) or restructure the claim to be about the overall system.
Cost realism: peptides scale your COGS
Premium peptide complexes can land between $400 and $2,200 per kilogram of active. At a real use level (1-3% of a peptide complex), this can add $1.50 to $4.00 per unit to your cost of goods. Build that into your hero-SKU pricing model before you fall in love with a peptide story you cannot afford to dose properly.
What a credible peptide claim looks like in 2026
Regulators and retailers are tightening on peptide claims. A defensible claim package in 2026 includes the supplier's published clinical study, a brand-funded user perception trial, and ideally a brand-funded instrumental study (cutometer, image analysis) on the final formula. Plan a 12 to 16 week claim-substantiation runway.
Key takeaways
- Pick peptide family by job-to-be-done, not by what looks impressive on the deck.
- Dose at the published clinical level or rewrite the claim — partial dosing is the #1 regulatory risk.
- Model peptide cost into hero-SKU pricing before formulation, not after.
- Plan a 12–16 week claim substantiation runway combining supplier, user-perception and instrumental data.
