Side-by-Side Comparison

AspectMatrixylSS-31 (Elamipretide)
MechanismMimics 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 DosageTopical: 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.
AdministrationTopical 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 EffectsVery well-tolerated. Rare mild irritation. Suitable for sensitive skin types.Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache.
