Matrixyl vs Adamax
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Matrixyl is the most widely used collagen-stimulating cosmetic peptide. As a matrikine — a fragment of type I procollagen — it signals skin cells to synthesize new collagen, elastin, and fibronectin, reducing wrinkle depth and improving skin firmness and elasticity.
- Adamax is a synthetic neuropeptide related to brain-derived neurotrophic factor (BDNF) signaling pathways. It is explored for cognitive enhancement, neuroprotection, and mood support, with proposed mechanisms involving TrkB receptor activation and enhancement of neuroplasticity similar to endogenous BDNF.
- Half-Life
- N/A — topical; sustained signaling effects on fibroblasts persist beyond single application
- Estimated 1-3 hours (short; peptide degradation)
- Admin Route
- Topical
- Subcutaneous, Intranasal (research)
