Science
Mechanism of Action
The primary active compound, spilanthol, modulates nerve receptors on the skin's surface, effectively impeding facial muscle contractions that contribute to the formation of wrinkles and expression lines. Beyond its myorelaxant effects, the extract is rich in antioxidant polyphenols like gallic acid, offering protection against environmental damage. It further supports skin structure by stimulating fibroblast biomechanical functions, leading to improved firmness and elasticity, while also providing skin conditioning, anti-inflammatory, and antimicrobial benefits.

Key findings
- 01 Studies indicate temporary alleviation of wrinkles through the inhibition of facial muscle contractions at concentrations from 0.1% to 20%.
- 02 Regular application of 2.0% to 5.0% concentrations demonstrates significant reduction in wrinkles by gently soothing nerve receptors, alleviating muscle tension, and visibly smoothing expression lines.
- 03 An in vivo study reported substantial improvements across various assessed parameters associated with skin wrinkles.
