Status unknown

Also known as: Acetyl hexapeptide-3, Acetyl Hexapeptide-8, Argireline NP, Hexapeptide 3, L4EL31FWIL, Acetyl hexapeptide 3, Acetyl-glu-glu-met-gln-arg-arg-amide, DTXSID201021291

Argireline (Acetyl hexapeptide-3, Acetyl Hexapeptide-8, Argireline NP) is classified under copper & cosmetic signal peptides.

What the research says

Aggregated from the cited literature below. We summarize sources — we don't author claims.

Argireline (also referred to as acetyl hexapeptide-8) is discussed in the provided literature as a synthetic topical peptide associated with wrinkle/anti-wrinkle research, and is also studied for physicochemical properties (including Cu(II) affinity), analytical detection in cosmetics, and biological/cytotoxicity assessment in vitro and in cells.

Mechanism (as reported)

A study reported that Argireline is patterned from the N-terminal end of SNAP-25 and proposed that it reduces wrinkle development and can interfere with SNARE complex formation and catecholamine release (PMID 23417317). Another study reported that mechanistic descriptions for Argireline include inhibition of neurotransmitter release at the neuromuscular junction and a “botox-like” effect (PMID 33482052).

Key findings (each cites a source)

  • A systematic review reported that the evidence base behind topical cosmeceutical peptides (including Argireline) was strong relative to other topical cosmeceutical categories for photoaging treatment, with many studies reaching Level Ib status in the evidence hierarchy. [PMID 39233460]
  • A clinical study in Chinese subjects reported that argireline showed significant anti-wrinkle effects for peri-orbital wrinkles versus placebo based on both subjective and objective evaluations. [PMID 23417317]
  • A study in aged mice induced by D-galactose reported histological improvements after argireline treatment, including changes in type I and type III collagen fibers. [PMID 23464592]
  • A study reported that Argireline-containing cosmetics could contain Argireline and an oxidized form, and used LC-MS/MS to detect these species and identify oxidation related to the methionine residue. [PMID 33482052]
  • Research investigated Cu(II) chelating/complex formation properties of Argireline and new Argireline derivatives using potentiometric titration and isothermal titration calorimetry, and used DFT calculations to propose likely Cu-peptide complex structures. [PMID 37752675]
  • A cytotoxicity/anti-proliferation study reported dose-dependent anti-proliferation effects of argireline solution in multiple human cell lines, and observed significant cytotoxicity at higher concentrations compared with doxorubicin in the study’s assays. [PMID 24644551]
  • A public interest analysis reported increased search volume for acetyl hexapeptide-8 (Argireline) in 2022 in the United States compared with earlier years, while noting it was less searched than Botox. [PMID 38376906]
  • A materials/instrumental study proposed a polydioxanone-embedded acetyl hexapeptide-8 system and reported instrumental observations consistent with a controlled release profile for Argireline under the study conditions. [PMID 38314369]
