Science
Mechanism of Action
This leaf water, or its active extracts, operates through several pathways to enhance skin health. It provides soothing effects, actively diminishing redness, itching, and overall discomfort by acting as a natural emollient that stabilizes the skin barrier. Its antibacterial properties target common acne-contributing bacteria such as *Propionibacterium acnes* and *Staphylococcus epidermidis*, assisting in inflammation reduction and promoting skin healing. As an antioxidant, due to its polyphenol content, it neutralizes free radicals to protect against environmental damage and premature aging. Furthermore, it incorporates moisturizing agents to improve skin elasticity and softness, functioning as a conditioning agent to leave skin feeling supple and deeply hydrated. Studies indicate its ability to inhibit pro-inflammatory mediators like TNF-α, COX-2, iNOS, and IL-6, while stimulating heme oxygenase-1 to prevent vascular inflammation.
