SNAP-8
Summary
Palmitoyl Dipeptide-6 is a synthetic dipeptide (lysine-threonine) with a palmitoyl fatty acid tail, designed to penetrate the skin barrier and stimulate the extracellular matrix components essential for skin firmness. It activates fibronectin and type IV collagen synthesis, improving skin density and firmness particularly in mature or sagging skin.
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.
