Active Peptides for the Next Generation of Skin.
Pepoderma supplies cosmetic-grade peptide actives to indie beauty brands, established skincare labs, and med-aesthetic OEMs. Every active ships with its INCI name, recommended use level, formulation notes, and stability data — so a chemist moves from sample to launch in weeks, not months.

The Pepoderma 4
A curated capsule of four cosmetic-grade peptides.
Pepoderma's atelier carries four actives — the canonical copper peptide, its hair-follicle analog, the expression-line peptide, and the collagen mimetic. Every entry has full INCI documentation, lot-specific data, and stability work in our reference aqueous serum on file.
The cosmetic-peptide canonical
Copper Tripeptide-1
Isolated from human plasma in 1973 and the textbook example of an endogenous copper-peptide complex, GHK-Cu is the reference active for cosmetic anti-aging formulation. Pepoderma ships it ≥99.0% HPLC with copper-content verification on every release packet so the diagnostic blue colour you receive is the same blue your finished serum should hold through shelf-life.

The hair-follicle copper variant
Copper Peptide (AHK · Cu)
The Ala-His-Lys structural analog of GHK-Cu, with the N-terminal glycine swapped for alanine. The substitution shifts the molecule's tissue-distribution preference toward the scalp and follicle, which is why AHK-Cu lives in hair-regrowth serums rather than dermal-repair creams. Mutually compatible with GHK-Cu in combined scalp-plus-skin programmes.

The expression-line wrinkle reducer
Acetyl Octapeptide-3
An 8-amino-acid acetylated peptide mimetic of the SNAP-25 N-terminus, designed as an extension of the classic Argireline molecule. Snap-8 lives in topical formulations targeting forehead, glabellar, and periocular expression lines. Typical use levels settle at 5–8 % of the finished product; we stock it kilo-scale for OEM finished-product runs.

The collagen-mimetic anti-aging peptide
Palmitoyl Pentapeptide-4
A palmitic-acid-conjugated pentapeptide based on the KTTKS fragment of human procollagen type I — the palmitoyl group is a delivery vehicle that lets the peptide cross the stratum corneum and reach dermal fibroblasts. Mechanistically complementary with GHK-Cu and Snap-8, the three peptides stack cleanly in a multi-active anti-aging serum.

The Pepoderma library is intentionally small — every active is one we have full INCI documentation and formulation-stability data for.

Brand Stories
From the formulators who ship with Pepoderma.
Pepoderma's partner-brand stories will live here as soon as our first cohort of finished-product launches give us consented quotes. The frame is reserved; the names are coming.
“[v0.2] Indie founder testimonials shipping when partner brands give us consented quotes — reserved for an indie clean-beauty house's first peptide serum launch.”
“[v0.2] Reserved for an R&D chemist at an established skincare line, speaking to the lot-specific data packet that lets them move a copper-peptide active into a finished formulation in weeks rather than months.”
“[v0.2] Reserved for a med-aesthetic OEM partner, speaking to the kilo-scale Snap-8 bulk lots that let them ship a finished expression-line serum to a clinic-channel customer on schedule.”
Where formulators find their next hero
Four doorways into the atelier.
Pepoderma supports brand programmes from the first sample request through the finished-product launch — and publishes the formulation references in between. Pick the doorway that matches where your programme is today.
Actives
4 INCI-documented cosmetic peptide actives — Copper Tripeptide-1, AHK-Cu, Acetyl Octapeptide-3, Palmitoyl Pentapeptide-4. Lot-specific data packet on every release.
Private Label
Sampling, custom-blend formulation, and finished-goods OEM for brand programmes. Three workflows — sample, custom blend, finished — depending on where your brand programme is in its development.
Lab
Formulation field guides, compatibility matrices, and use-level references for every featured active. Designed to live on a chemist's bookmarks bar.

Every batch, fully documented.
Every shipment leaves the atelier with the batch's Certificate of Analysis, HPLC purity, mass-spec identity, and microbial limits. INCI verification, stability data in our reference aqueous serum, and copper-content verification (for copper-peptide actives) are included so a chemist answers their own QA before the first sample fills a laboratory beaker.
