Syn-Coll vs KPV
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Syn-Coll is a palmitoylated tripeptide (Palmitoyl Tripeptide-5) that mimics thrombospondin-1 to activate TGF-beta, the primary growth factor driving collagen synthesis in the dermis. It is one of the most mechanistically direct collagen-stimulating peptides in cosmetic formulations.
- KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
- Half-Life
- Extended (lipid depot in stratum corneum)
- Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
