Syn-Coll
Summary
SNAP-8 is a synthetic octapeptide cosmetic ingredient that reduces the depth of expression lines and wrinkles by competitively inhibiting the SNARE complex involved in acetylcholine release at neuromuscular junctions, providing a topical 'Botox-like' effect.
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.
