Science

Mechanism of Action

This extract operates by enhancing skin health and appearance through a multi-pronged approach. It forms a protective barrier on the skin's surface, which significantly aids in moisture retention, promoting optimal hydration. Rich in active compounds such as polyphenols, tannins, and suberin, it delivers robust antioxidant and anti-inflammatory properties, safeguarding the skin from environmental stressors. Suberin, composed of hydroxycarboxylic acids, specifically contributes to a noticeable smoothing effect on the skin's texture, while phenolic acids and terpenes further bolster its antioxidant capacity. Additionally, it provides soothing, anti-aging, anti-redness, and skin-firming benefits.
