Science

Mechanism of Action

This extract operates through several pathways to enhance skin vitality and resilience. Its robust antioxidant capacity neutralizes free radicals, mitigating environmental damage and supporting cellular integrity. It actively inhibits collagenase and elastase enzymes, thereby preserving the skin's structural proteins and maintaining firmness and elasticity. Furthermore, it exhibits anti-inflammatory and antibacterial properties, reducing irritation and combating microbial imbalances, particularly against Gram-positive bacteria. The extract also functions as a tyrosinase inhibitor, potentially aiding in melanin formation control and skin tone enhancement, and acts as an anti-sebum agent to regulate oil production. Its astringent properties assist in refining complexion by aiding in the removal of dead skin cells and impurities, while also forming a protective layer to reduce transepidermal water loss and shield against external stressors.
