ACETYL HEXAPEPTIDE-76 AMIDE.

Valuable / SKIN CONDITIONING

This precision peptide, also known as Argireline, targets the formation of expression lines by influencing muscle contractions. Beyond its prominent wrinkle-smoothing effects, it also significantly enhances skin hydration, firmness, and overall barrier function, positioning it as a multifaceted ingredient for advanced age management.

Anti-aging Wrinkle Reduction Skin-conditioning Humectant Skin Firming

Science

Mechanism of Action

Acetyl Hexapeptide-76 Amide operates by competitively interfering with the SNAP25 protein, a crucial component of the SNARE complex. This complex is vital for the release of neurotransmitters, such as acetylcholine, which trigger muscle contractions. By disrupting the proper assembly and stabilizing the SNARE complex, the peptide effectively reduces calcium-dependent neurotransmitter release, thereby mitigating facial muscle activity and diminishing the appearance of dynamic wrinkles and expression lines.

Key findings

  1. 01 A clinical study demonstrated that a 0.005% concentration, applied twice-daily for 4 weeks, measurably increased stratum corneum water content and improved skin firmness by decreasing anisotropy in facial skin.
  2. 02 Further clinical evidence highlights its capacity to accelerate facial muscle relaxation by up to 31%, visibly reduce the appearance of fine lines by up to 14.7%, and boost type I collagen production in aged skin by up to 25.9%, resulting in a 13.8% increase in skin plumpness. Additional observed benefits include enhanced skin hydration, improved texture and tone, soothing of irritated skin, and strengthening of the skin barrier.
