What it is
An extract obtained from the flowers of Melilotus officinalis, also known as yellow sweet clover. It contains coumarin derivatives and flavonoids that give it mild anti-inflammatory and antioxidant properties.
How it works
The flavonoids in sweet clover extract help neutralize free radicals, while coumarin compounds may support microcirculation by strengthening capillary walls. This can reduce the appearance of redness and puffiness when applied topically.
Pros
Gentle soothing
The extract is mild and unlikely to cause irritation, making it suitable for sensitive skin types when formulated correctly.
Circulation support
May help reduce puffiness, especially around the eyes, by supporting healthy microcirculation in the skin.
Cons and cautions
Limited evidence
Most benefits are based on traditional use and lab studies; robust human clinical trials are lacking.
Formulation sensitivity
Coumarin content can be irritating if the extract is not properly processed or used at too high a concentration.
Best for
