Matrixyl vs Substance P
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Matrixyl
Matrixyl (Palmitoyl Pentapeptide-4) is a signal peptide that stimulates collagen and extracellular matrix production. It is one of the most well-studied anti-aging peptides with proven efficacy for wrinkle reduction.
Full details →Substance P
Substance P is an 11-amino acid neuropeptide involved in pain transmission, inflammation, and various neurological processes. While not used therapeutically itself, understanding it is crucial for pain research.

| Aspect | Matrixyl | Substance P |
|---|---|---|
| Mechanism | Mimics collagen breakdown fragments, triggering fibroblasts to produce new collagen, elastin, and other matrix components. Essentially tricks skin into repair mode without actual damage. | Binds primarily to NK1 receptors to transmit pain signals from peripheral nerves to the CNS. Also promotes inflammation, causes vasodilation, and stimulates immune cells. |
| Typical Dosage | Topical: 2-8% concentration in serums and creams. Matrixyl 3000 combines it with Palmitoyl Tetrapeptide-7 for enhanced effects. | Not used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea. |
| Administration | Topical application 1-2 times daily. Can be combined with other actives like retinol, vitamin C, and other peptides. | Research compound only. Therapeutic applications focus on blocking rather than administering Substance P. |
| Side Effects | Very well-tolerated. Rare mild irritation. Suitable for sensitive skin types. | Administration would cause pain, inflammation, and neurogenic responses. Not given therapeutically. |
