What it is
A natural extract obtained from the flowers of Lotus corniculatus, a flowering plant in the pea family. The extract contains flavonoids and phenolic compounds that are believed to have antioxidant and anti-inflammatory activity.
How it works
The flavonoids in the extract can scavenge free radicals, reducing oxidative stress on the skin. This may help protect skin cells from environmental damage and support a calmer, more even complexion. Its soothing properties are thought to come from its ability to modulate inflammatory pathways, though the exact mechanism in topical use is not fully understood.
Pros

Soothing potential
May help calm minor redness or irritation, offering a mild anti-inflammatory effect for everyday use.
Cons and cautions
