Palmitoyl tripeptide-1 (INCI: PALMITOYL TRIPEPTIDE-1; CAS 147732-56-7) is a Matrikine signal peptide supplied by Plamed at ≥98.0% HPLC purity with peptide content ≥80.0%. Used at 0.001%–0.1%, it triggers collagen synthesis and supports firmness, and it is usually paired with palmitoyl tetrapeptide-7.

In short: Palmitoyl Tripeptide-1 is a classic collagen-promoting signal peptide and a core active for root-cause anti-aging, firming and wrinkle-reducing skincare. Also known as Palmitoyl Oligopeptide, it belongs to the Matrikine family — peptides derived from the body's own ECM-breakdown fragments.
How it works. It mimics the signal fragments released during collagen degradation (represented by type I collagen-related signal sequences), sending "collagen regeneration" signals to skin fibroblasts and triggering the dermis's self-repair mechanism. It regulates collagen-synthesis pathways such as TGF-β/Smad, upregulates type I/III collagen, elastin, fibronectin and glycosaminoglycans, and helps regulate MMP activity to reduce excessive collagen degradation — a two-way mechanism of "promoting synthesis + inhibiting degradation".
Barrier co-benefit. By promoting ECM reconstruction it improves the skin microenvironment and keratinocyte function, upregulating barrier proteins such as filaggrin and reducing transepidermal water loss (TEWL).
How it is made. Cosmetic-grade Palmitoyl Tripeptide-1 is chemically synthesized; Plamed produces it by Solid Phase Peptide Synthesis (SPPS), supplying a high-purity powder with HPLC purity ≥98.0% and peptide content internal control ≥80.0% (batch tested up to 85.1%).
The differentiated quality metric: scientific chloride content control. Chloride ions arise from salt formation and neutralization during peptide manufacturing. The industry's conventional free-HCl index is calculated indirectly via chloride conversion, involving salt-form assumptions and conversion errors. Plamed analyzed the potential salt-forming sites of Palmitoyl Tripeptide-1 and set a scientific control range (≤15.0%) with reference to the theoretical maximum salt-forming chloride content — accurate, unambiguous data that reduces formulation fluctuation risk, shortens adjustment cycles and improves long-term finished-product stability.
Where it fits. Signal-activated anti-aging that improves dry lines, fine lines, sagging and elasticity loss from collagen decline — widely used in high-end anti-aging, firming, wrinkle-reducing and barrier-repair products.
How is palmitoyl tripeptide-1 made? SPPS versus LPPS
Conclusion first: Palmitoyl Tripeptide-1 is chemically synthesized, and Plamed's optimized SPPS route delivers high purity, high peptide content and scientifically controlled chloride residues.

How to read this specification. Three numbers matter most:
Purity ≥98.0% (HPLC) — chemical identity of the peptide fraction; Plamed batch tested up to 98.9%.
Peptide content ≥80.0% (HPLC) — whole-sample share of active peptide; batch tested up to 85.1%, above the release specification.
Chloride content ≤15.0% — the differentiated metric. Set by salt-forming-site analysis with reference to the theoretical maximum salt-forming chloride for this specific peptide, it replaces the industry's indirect free-HCl conversion index. The result: small batch-to-batch variation and unambiguous compatibility data for formulators.
A batch-specific COA is provided with every order.
Plamed produces palmitoyl tripeptide-1 powder through a controlled four-stage SPPS process:
1. Raw material — protected amino acid building blocks and palmitic acid derivatives released against incoming specifications.
2. Synthesis — stepwise peptide coupling builds the GHK tripeptide sequence; the palmitoyl group is attached under controlled conditions.
3. Purification — combined purification removes uncoupled fragments and process-related impurities; purity, peptide content and chloride are verified by HPLC and ion testing.
4. Drying & product release — lyophilization yields a solvent-free white-to-off-white powder, packed in sealed pharmaceutical bottles and released only after COA verification of purity, peptide content, chloride, heavy metals and microbiological limits.
What does palmitoyl tripeptide-1 do for skin? Collagen, firmness and barrier
In short: palmitoyl tripeptide-1 is the "construction" peptide of the Matrikine family. Mimicking signal fragments generated during ECM degradation, it sends "collagen regeneration" signals to fibroblasts, regulates TGF-β/Smad pathways, and upregulates type I/III collagen, elastin, fibronectin and glycosaminoglycans — supporting dermal structural integrity and density, filling dry lines and fine lines, and improving firmness and elasticity.
Anti-photoaging: structural support + microenvironment regulation
UV-induced photoaging drives extrinsic skin aging through oxidative stress, inflammation and increased collagen degradation. Palmitoyl Tripeptide-1 counters via two routes: it reduces UV-induced ROS and inflammation, and downregulates MMPs to slow collagen/elastin degradation while promoting ECM synthesis and metabolic balance — maintaining dermal stability and delaying photoaging-related structural deterioration.

Barrier repair and ECM improvement
It promotes ECM reconstruction, optimizes keratinocyte function and upregulates filaggrin, loricrin and other barrier proteins, reducing TEWL and strengthening the skin barrier fundamentally — suitable for damaged-skin repair.

Synergistic anti-aging with Palmitoyl Tetrapeptide-7
The pair forms a "build & protect" closed loop. Palmitoyl Tripeptide-1 (construction) stimulates fibroblasts to synthesize new collagen, elastin and ECM; Palmitoyl Tetrapeptide-7 (protection) regulates inflammation pathways (e.g. NF-κB), reduces pro-inflammatory factors and downregulates MMPs to block collagen degradation. Their mechanisms are highly complementary, with strong performance in wrinkle improvement, elasticity enhancement and texture optimization.

Why formulators shortlist it:
As the best-characterized collagen-building signal peptide, palmitoyl tripeptide-1 is a backbone of multi-peptide anti-aging serums and firming eye creams, and is frequently listed among proven anti-aging ingredients to look for in wrinkle, firming and barrier-repair formulas. At 0.001–0.1% use level it layers well with Palmitoyl Tetrapeptide-7, ceramides, niacinamide and hyaluronic acid.
Palmitoyl Tripeptide-1 achieves anti-aging effects at low addition levels and is widely used across skincare formats — high-end anti-wrinkle serums, firming creams, eye care, anti-photoaging products, barrier-repair emulsions and full-category skincare.

Q1: What is Palmitoyl Tripeptide-1?
A: Palmitoyl Tripeptide-1 (CAS 147732-56-7, INCI: PALMITOYL TRIPEPTIDE-1) is a Matrikine signal peptide — palmitic acid linked to the GHK tripeptide sequence. Also known as Palmitoyl Oligopeptide, it sends "collagen regeneration" signals to fibroblasts and is one of the best-characterized collagen-building peptides in cosmetics.
Q2: What are the benefits of Palmitoyl Tripeptide-1 for skin?
A: Its documented skin benefits: stimulating collagen synthesis (type I/III collagen, elastin, fibronectin, glycosaminoglycans) via TGF-β/Smad-related signaling; regulating MMP activity to reduce collagen degradation; supporting barrier repair via filaggrin upregulation and reduced TEWL; and protecting against photoaging by reducing UV-induced ROS and inflammation. In short: wrinkle reduction, firming and barrier support in one peptide.
Q3: Is Palmitoyl Tripeptide-1 the same as Matrixyl?
A: No. Palmitoyl Tripeptide-1 is the collagen-building component of the Sederma trademarked blends — Matrixyl® is based on Palmitoyl Pentapeptide-4, and Matrixyl 3000® is a blend of Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7. Both trademarks are third-party; Plamed supplies the INCI ingredients themselves (PMKZ3001 / PMKZ2801 / PMKZ2901), giving formulators full control over purity, ratio and cost.
Q4: How does Palmitoyl Tripeptide-1 work with Palmitoyl Tetrapeptide-7?
A: They are highly complementary: Tripeptide-1 is the "build" peptide (stimulates new collagen and ECM synthesis), while Tetrapeptide-7 is the "protect" peptide (regulates NF-κB-related inflammation and downregulates MMPs to block collagen degradation). Combined, they form a build-and-protect anti-aging loop recommended at the formulation stage.
Q5: What is the recommended dosage in skin care?
A: The reference dosage is 0.001%–0.1% for Palmitoyl Tripeptide-1 with purity ≥98.0%. It is added below 45 °C at the final stage of formulation, and is not compatible with strong acids, strong alkalis, strong oxidizers, acyl chlorides or acid anhydrides.
