Science
Mechanism of Action
The primary active compound, spilanthol, modulates facial muscle activity to temporarily reduce contractions, thereby smoothing the appearance of fine lines and wrinkles. Beyond this 'botox-like' effect, it actively stimulates fibroblasts, promoting the synthesis of collagen for enhanced skin firmness and elasticity. Rich in antioxidants, it defends against free radical damage and mitigates hyperpigmentation, while its anti-inflammatory properties soothe the skin by inhibiting pro-inflammatory cytokines. Furthermore, it aids in moisture retention and exhibits antimicrobial action for a clearer complexion.
