What it is
An extract derived from the flowers, leaves, and stems of Bupleurum falcatum, a plant native to East Asia. It contains compounds like saikosaponins and flavonoids, which are believed to have anti-inflammatory and antioxidant activity.
How it works
The saikosaponins in Bupleurum extract are thought to reduce the production of pro-inflammatory signals in skin cells, helping to calm irritation. Its flavonoids scavenge free radicals, which can help protect skin from oxidative damage caused by UV and pollution.
Pros

Antioxidant support
Contains flavonoids that can help protect skin from free radical damage caused by UV and pollution.
