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.
Acetyl Tetrapeptide-5 is a synthetic peptide used in cosmetics primarily to reduce periorbital puffiness and improve skin elasticity by inhibiting angiotensin-converting enzyme activity and reducing fluid accumulation and glycation. It is commonly found in eye creams and anti-aging formulations.
