The peptide

N-Prolyl Palmitoyl Tripeptide-56 Acetate: Reconstructing Dermal Morphology for Targeted Line Reduction

N-Prolyl Palmitoyl Tripeptide-56 Acetate is an advanced synthetic matrikine lipopeptide that upregulates longevity pathways to re-establish critical connections between the fibroblast nucleus and the extracellular matrix. This action stimulates the synthesis of Collagen I, III, IV, VI, and fibronectin, enabling it to reconstruct dermal morphology from the inside out. In cosmetic applications, it is uniquely positioned to target the reduction of “sad” vertical expression lines—such as frown lines, marionette lines, and nasogenian folds—as well as crow’s feet.

Market context: — N-Prolyl Palmitoyl Tripeptide-56 Acetate is predominantly recognized as the peptide found in Matrixyl® Morphomics™-class actives. It is positioned to compete with, or complement, other matrikine-class peptides like those found in Matrixyl 3000 and Matrixyl Synthe’6-class actives, by differentiating itself through highly targeted action on vertical expression lines and dermal connectivity, rather than generalized skin elasticity. Formulate Labs supplies the generic INCI N-Prolyl Palmitoyl Tripeptide-56 Acetate only and does not sell trade-name SKUs.

We supply it at 0.02% standard or 0.2% lab concentrate in glycerin or Sea Kelp Bioferment carriers.

Published research

Peer-reviewed literature for due diligence.

N-Prolyl Palmitoyl Tripeptide-56 Acetate (Matrixyl Morphomics) has peer-reviewed in-vitro and clinical publications on ECM architecture, longevity-gene modulation, and oxidative stress. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.

Compliance & safety

The fine print, in plain English.

What it’s for
Cosmetic raw material - leave-on hair-care formulations (scalp serums, hair tonics, leave-on hair lotions, density-positioned conditioning treatments) at the use rates above; also acceptable in rinse-off cosmetic products and skincare formats where a peptide-based "supports the look of fuller hair" / scalp-comfort positioning is intended. Not a finished consumer product; not for ingestion, injection, or unsupervised topical use outside a formulated finished product.
Claims guidance
Cosmetic structure / function language only (e.g. softens the look of expression lines, supports a smoother appearance). Avoid filler / injectable language (“replaces fillers”, “restores facial volume” as a medical claim). Do not make therapeutic claims. The peptide is studied in cosmetic in-vitro and panel work; downstream finished-product claims must be substantiated by the brand.
Storage
  • Store between 2-25 °C in original sealed container away from direct light.
  • Cold storage extends shelf life by ~50% relative to room temperature.
  • Once opened, use within the period stated on the COA.
Regulatory
  • INCI: N-Prolyl Palmitoyl Tripeptide-56 Acetate (per ICID and PCPC dictionary).
  • Not classified as hazardous based on currently available information per OSHA HazCom 2012 / GHS.
  • Compatible with FDA cosmetic regulations and EU 1223/2009 for the intended use.
  • SDS section 16 disclaimer applies; see the per-recipe SDS for the full classification.
Sensitivity
N-Prolyl Palmitoyl Tripeptide-56 Acetate is generally well-tolerated in cosmetic use at the rates above; the supplier’s HET-CAM and AMES studies on the peptide indicate non-irritating and non-mutagenic behavior at industry-standard concentrations. The peptide is light-sensitive: store and ship in opaque containers, and avoid prolonged exposure to direct sunlight in finished formulations. Avoid prolonged contact with strong oxidisers, sulfuric or phosphoric acids, acetic anhydride, sustained heat above 45 °C, and prolonged exposure to pH > 7.0 - any of these can hydrolyze the peptide and reduce in-formula activity. Patch-test finished formulations per standard cosmetic protocol.
