Direct Answer
Matrixyl 3000 is a cosmetic peptide blend of palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7. A cited 12-week human study of a multi-component formula containing both peptides reported measured skin improvements; because the formula included additional actives, effects cannot be attributed to the peptide blend alone.

Key Takeaways
- Matrixyl 3000 is a blend of palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7
- Cited human evidence is from a multi-ingredient formula
- Effects cannot be attributed to the peptide blend alone
Scientific Overview
In Plain English
Matrixyl 3000 is a blend of two peptides (palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7) used in anti-aging skincare. A 12-week human study of a product containing these peptides plus other ingredients reported better skin hydration, elasticity, and fewer visible fine lines, but the product had several actives, so the result is for the whole formula.
Scientific Details
Matrixyl 3000 combines palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7. A 12-week controlled human study of a multi-component eye cream containing both peptides (with yeast and rice ferment filtrate and N-acetylneuraminic acid) reported improvements in measured hydration, elasticity, and the appearance of fine lines and wrinkles, alongside in vitro fibroblast proliferation and collagen and elastin synthesis for the active complex. The multi-ingredient design means effects cannot be attributed to the peptide blend alone.
How It Works
The blend is described in relation to fibroblast activity and matrix-protein synthesis; cited evidence evaluated it within a multi-component formulation rather than in isolation.
Mechanism of Action
Matrix-protein signaling (formulation-level)
cell
In a multi-component study, the active complex was associated with fibroblast proliferation and collagen and elastin synthesis in vitro.
Evidence Level
Human Evidence
A 12-week controlled study of a multi-ingredient formula containing the blend reported improvements in measured hydration, elasticity, and fine-line and wrinkle appearance.
Cell Evidence
In vitro work reported fibroblast proliferation and collagen and elastin synthesis for the active complex.
Limitations
Evidence is from a multi-ingredient formulation; effects cannot be attributed to the Matrixyl 3000 peptide blend alone. The cited study is manufacturer-funded (Mageline Biology Tech).
