Science
Mechanism of Action
Centella Asiatica Leaf Water actively benefits the skin through its rich composition of triterpenoids like Madecassic Acid and Asiaticoside. It reduces inflammation and oxidative stress via its anti-inflammatory and antioxidant properties, mitigating redness and cellular damage. The ingredient stimulates fibroblast activity, enhancing collagen synthesis to support wound healing, minimize scarring, and improve skin firmness and elasticity. Furthermore, it aids in moisture retention by encouraging natural hyaluronic acid production and fortifying the skin barrier, while also contributing to balanced pH and sebum secretion.
Research
Clinical Evidence
High confidenceOptimal efficacy for Centella Asiatica Leaf Water is frequently achieved at high concentrations, with common product formulations featuring 75-85%. Related clinical studies have shown active compounds like madecassoside to be effective at 0.1%, and Centella Asiatica extract at 5%.
