Matrixyl vs SS-31 (Elamipretide)
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 →SS-31 (Elamipretide)
SS-31, also known as Elamipretide or Bendavia, is a mitochondria-targeted tetrapeptide. It has been studied extensively for mitochondrial diseases, heart failure, and age-related decline in mitochondrial function.

| Aspect | Matrixyl | SS-31 (Elamipretide) |
|---|---|---|
| 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. | Concentrates in the inner mitochondrial membrane where it binds to cardiolipin, stabilizing electron transport chain function, reducing reactive oxygen species, and improving ATP production efficiency. |
| Typical Dosage | Topical: 2-8% concentration in serums and creams. Matrixyl 3000 combines it with Palmitoyl Tetrapeptide-7 for enhanced effects. | Clinical trials have used IV infusions of 0.25mg/kg for acute conditions. Subcutaneous dosing protocols for research use typically range from 1-5mg daily. |
| Administration | Topical application 1-2 times daily. Can be combined with other actives like retinol, vitamin C, and other peptides. | Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions. |
| Side Effects | Very well-tolerated. Rare mild irritation. Suitable for sensitive skin types. | Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache. |
