Thermal Spring Water
Water from mineral springs, used as a face mist and as a base in skincare. Its benefits are not yet checked by Drop.
What it does
Thermal spring water comes from natural springs and carries dissolved minerals that differ from spring to spring. It is used as a face mist, a toner base and a base for other products. Drop cites one review of it but has not read more than its title, so Drop makes no claim yet about soothing or barrier effects.
