|---|---|---|
| Typical Concentration | Typically used at 5-10% concentration. Apply twice daily to expression line areas (forehead, around eyes, between brows). Effects visible after 2-4 weeks. Must be used continuously — effects reverse when stopped. | Concentrations: 0.01-1% as an isolated compound. Products with pure madecassoside are common in K-beauty and French pharmacy brands (La Roche-Posay Cicaplast). Apply morning and night. Excellent as a recovery treatment post-retinoid or post-procedure. |

Mechanism of Action
Argireline (Acetyl Hexapeptide-3)
Argireline (acetyl hexapeptide-3) mimics the C-terminal region of SNAP-25, a core SNARE complex component. The SNARE complex (SNAP-25, syntaxin, synaptobrevin) mediates vesicle fusion at the neuromuscular junction for acetylcholine release. Argireline competes with SNAP-25 for syntaxin binding, partially disrupting SNARE assembly and reducing neurotransmitter exocytosis. This decreases acetylcholine release and attenuates facial muscle contraction intensity. The effect is dose-dependent, localized, and reversible—unlike botulinum toxin's enzymatic cleavage of SNAP-25. Clinical studies show ~30% wrinkle reduction versus 80%+ with injectable neurotoxins. Provides non-invasive expression line softening.
Madecassoside
Madecassoside (triterpene glycoside from Centella asiatica) inhibits NF-kappa B nuclear translocation by preventing I-kappa B alpha degradation, suppressing transcription of pro-inflammatory cytokines (TNF-alpha, IL-1beta, IL-6) and COX-2. Activates Nrf2, upregulating antioxidant enzymes (heme oxygenase-1, NQO1, glutathione peroxidase). Stimulates collagen type I synthesis through TGF-beta/Smad3 signaling in fibroblasts, upregulating COL1A1. Promotes keratinocyte migration (wound closure) by enhancing integrin expression and matrix metalloproteinase activity. Inhibits hyaluronidase, preserving skin hyaluronic acid. Reduces VEGF expression, inhibits MMP-1. Comprehensive: anti-inflammatory, antioxidant, pro-collagen, wound-healing. Used in pharmaceutical wound care (Madecassol) and K-beauty. Ideal for post-procedure recovery, retinoid irritation, sensitive skin.

Full Profiles

Known as 'topical Botox,' Argireline is a peptide that reduces the appearance of expression lines by partially inhibiting the SNARE complex — the same mechanism targeted by botulinum toxin, but through topical application rather than injection. The effect is much milder than Botox (roughly 30% wrinkle reduction vs 80%+) but provides a non-invasive option for forehead lines, crow's feet, and frown lines.
Madecassoside →
A purified triterpene glycoside from Centella asiatica that is the primary anti-inflammatory and wound-healing compound in the 'cica' family. While Centella asiatica extracts contain a mix of four triterpenes, isolated madecassoside provides the most potent soothing and barrier-repair effects. It is particularly effective for post-procedure recovery, sensitive skin, and skin exposed to environmental stressors like pollution and UV.
