Argireline (Acetyl Hexapeptide-8) for Wrinkle Reduction & Expression Lines — Skin & Hair
Topical peptide that reduces expression wrinkles through neurotransmitter inhibition, often called 'topical Botox'.
Overview
Argireline (Acetyl Hexapeptide-8) is a hexapeptide that functions as a neurotransmitter inhibitor, reducing the depth of wrinkles caused by repeated facial expressions. It works by inhibiting SNARE complex formation, which is essential for neurotransmitter release at the neuromuscular junction. This mechanism is similar to botulinum toxin but delivered topically without injections. Clinical studies show up to 30% reduction in wrinkle depth with consistent use. Argireline is particularly effective for forehead lines, crow's feet, and expression wrinkles. It's safe for topical use and well-tolerated in cosmetic formulations.
Indications
- Expression wrinkles (forehead, crow's feet, frown lines)
- Wrinkle prevention in aging skin
- Non-invasive alternative to botulinum toxin injections
- Combination with other anti-aging peptides
- Smooth skin texture improvement
Mechanism of Action
Muscle contractions from facial expressions cause dynamic wrinkles in forehead, around eyes, and mouth
Dosing
| Compound | Dose | Frequency | Notes |

| Argireline 10% | Apply to specific wrinkle areas | Once or twice daily | Higher concentration for stubborn expression lines |
