Science
Mechanism of Action
The extract's mechanism involves several key components. Tannins contribute astringent and antibacterial effects while forming a protective barrier on the skin. Flavonoids, alongside phenolic compounds like gallic, caffeic, and chlorogenic acids, provide antioxidant protection. Ellagitannins, such as gemin A and casuarinin, are crucial for anti-inflammatory action by inhibiting reactive oxygen species, proteases (elastase, MMP-9), chemokines, and cytokines (IL-8, IL-1β), also acting as redox-modulators to decrease intracellular superoxide levels. Essential oils, including eugenol, enhance antimicrobial defense, and linoleic and linolenic acids from the seeds support skin barrier integrity.

Safety
Safety Profile
The safety profile for Geum Urbanum Extract lacks comprehensive data, with oral, parenteral, and dermal toxicity not yet fully determined. There is a noted likelihood of skin irritation, inflammation, or dryness, primarily attributed to its tannin content. This risk may be amplified when formulated alongside other potentially problematic ingredients.
