What it is
An extract made from the leaves of Melilotus officinalis, a plant also known as yellow sweet clover. It contains flavonoids, phenolic acids, and coumarin derivatives that contribute to its antioxidant and anti-inflammatory activity.
How it works
The flavonoids in sweet clover leaf act as antioxidants, neutralizing free radicals that can damage skin cells. Its coumarin compounds are thought to help reduce inflammation and soothe irritation by calming the skin's immune response. In a formula, it works best alongside other soothing ingredients.
