Argireline
Also known as: Acetyl Hexapeptide-3, Acetyl Hexapeptide-8, Argireline Amplified
A synthetic hexapeptide developed by the Spanish biotech company Lipotec, marketed as a topical alternative to Botox. It reduces the appearance of expression lines by partially limiting muscle contraction signals at the cellular level. It is available in many over-the-counter skincare products.
How it works
Argireline works by targeting the SNARE protein complex, which is needed for muscle contraction at the cellular level. Botox does something similar but much more potently by blocking nerve signals entirely. Argireline only partially inhibits the SNARE complex when applied topically, so the effect is much milder. It reduces the intensity of facial muscle contractions that cause expression lines, without freezing the face.
Common uses
- Expression line and wrinkle reduction
- Crow's feet treatment
- Forehead line softening
- Non-invasive Botox alternative
Side effects
- Very well-tolerated
- Mild irritation, redness, or tingling in some users
- Rare allergic reactions
- No systemic side effects from topical use
- Effects are much milder than Botox and require daily application
Key research
- Key study showed 30% reduction in wrinkle depth with 10% Argireline solution applied over 30 days
- Randomized placebo-controlled study in Chinese subjects showed 48.9% anti-wrinkle efficacy vs 0% in placebo
- Double-blind trial comparing Argireline and Matrixyl for crow's feet reduction showed both peptides effective
- 2025 review noted statistical significance of results has been inconsistent across studies
Safety notes
- Available in over-the-counter skincare products without a prescription
- No known serious side effects or toxicity
- The Ordinary offers Argireline Solution 10% for around $10
- Results are more subtle than injectable Botox and require consistent daily use
- Not regulated as a drug or peptide therapy
