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 Tripeptide-1 is a synthetic palmitoylated peptide (sequence Gly-His-Lys) used in cosmetics to signal fibroblasts and support collagen and extracellular matrix synthesis. It is commonly combined with other peptides in anti-aging and firming formulations.
