Matrixyl vs DSIP
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.
- DSIP is an endogenous neuropeptide originally isolated from rabbit cerebrospinal fluid that induces delta-wave (deep) sleep. It also modulates stress response, cortisol regulation, and LH secretion, making it valuable for sleep optimization and stress management.
- Half-Life
- N/A — topical; sustained signaling effects on fibroblasts persist beyond single application
- ~30–60 minutes; however downstream sleep effects last 4–6 hours
- Admin Route
- Topical
- SubQ, IV, Intranasal
