Matrixyl vs Cardiogen
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.
- Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.
- Half-Life
- N/A — topical; sustained signaling effects on fibroblasts persist beyond single application
- Short (minutes); gene-regulatory effects persist longer
