What it is
A natural extract derived from the fruit of the Gleditsia japonica tree, also known as Japanese honey locust. It contains compounds like flavonoids and saponins that are thought to have antioxidant and anti-inflammatory activity.
How it works
In a cosmetic product, this extract is believed to work by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells), and by calming inflammatory pathways in the skin. The saponins may also provide mild cleansing or foaming properties in wash-off products.
