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.
Copper Tripeptide-1 (GHK-Cu) is a copper-bound peptide used in skincare for its reported ability to support collagen and elastin synthesis, wound healing, and antioxidant activity. It is considered a bioactive cosmetic ingredient targeting signs of skin aging.
