Summary

Soothing Moisturizing Humectant Antioxidant Anti-inflammatory Skin Barrier Support

Science

Mechanism of Action

This extract's efficacy stems primarily from its high mucilage content, a naturally occurring polysaccharide. This gel-like substance creates a protective, moisture-retaining barrier on the skin, significantly enhancing hydration and providing a soothing effect. Furthermore, its anti-inflammatory compounds help reduce redness and calm irritated or sensitive skin by stimulating anti-inflammatory cellular activity. Flavonoids and phenolic compounds contribute potent antioxidant protection, neutralizing free radicals and potentially mitigating UV-induced DNA damage. It also supports the skin barrier and helps preserve the skin's natural hyaluronic acid levels, complementing its hydrating actions. Evidence also suggests antibacterial activity against certain bacteria like Staphylococcus aureus and a role in stimulating wound healing processes.
