SNAP-8- Summary
- Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) that stimulates melanin production (skin tanning), suppresses appetite, and enhances sexual function. It is not FDA-approved and has significant safety concerns including mole changes and cardiovascular effects.
- 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.
