What it is
Isodonis japonicus extract is an alternate INCI naming for extract of the Japanese mint-family herb Isodon japonicus. It is used in cosmetics as a skin-conditioning and soothing botanical, drawing on the plant's content of diterpenoids and phenolic constituents. It appears as a supporting ingredient at modest concentrations rather than as a headline active.
Safety & warnings
Generally well tolerated in leave-on products at the low levels typically used. As with other mint-family botanicals, sensitivity is possible in predisposed individuals, and composition can vary with the source plant material.
Origin & sourcing
Plant-derived from Isodon japonicus, a perennial herb of the Lamiaceae (mint) family native to East Asia.
