What it is
A natural extract derived from the tuberous roots of the Butea superba plant, a climbing vine native to Southeast Asia. It contains flavonoids and other polyphenolic compounds.
How it works
The flavonoids in Butea superba extract act as antioxidants, neutralizing free radicals that can damage skin cells. Some lab studies indicate it may also influence enzymes related to collagen breakdown, but this has not been confirmed in human skin.
