Science
Mechanism of Action
This extract operates through a multi-faceted approach, leveraging bioactive compounds such such as rutin and rosmarinic acid. It delivers robust antioxidant defense by neutralizing free radicals and mitigating oxidative stress. Its anti-aging efficacy is attributed to significant collagenase inhibition, preserving dermal structure and elasticity, alongside anti-tyrosinase activity that helps regulate melanin production for improved skin tone. Additionally, its inherent moisturizing and anti-inflammatory qualities contribute to optimal skin hydration and a visibly calmer appearance.
