Acetyl Hexapeptide-8
Acetyl Hexapeptide-8 (also known as Argireline or acetyl hexapeptide-3) is a synthetic peptide that mimics the N-terminal end of SNAP-25, mildly inhibiting neurotransmitter release to reduce the appearance of expression lines. It is marketed as a topical alternative to injectable neuromodulators, though its effects are subtler.
Palmitoyl Tetrapeptide-7 is a palmitoylated synthetic peptide used in cosmetic formulations, primarily marketed to help reduce inflammatory signaling and support a more even, firmer skin appearance. It is commonly paired with other peptides such as Palmitoyl Tripeptide-1 in anti-aging products.
