What it is
Kanzou Furabonoido refers to a flavonoid-rich fraction extracted from the root of licorice (kanzou is the Japanese term for licorice). It is valued in skincare for its antioxidant and skin-soothing properties and is commonly included in Japanese formulations as a botanical conditioning agent. In sunscreens it supports the overall skin-care profile rather than contributing to UV filtration.
Safety & warnings
Licorice-derived botanicals are generally well tolerated and are often chosen for their soothing character. As with any plant extract, individuals with very sensitive skin may occasionally react, so patch testing is reasonable.
Origin & sourcing
Naturally derived from licorice root (Glycyrrhiza species), isolated as a flavonoid-enriched fraction.
