Yunohana Onsen Powder
Sourced from the mineral deposit on Mt Yakedake in the northern part of the Japanese Alps, this mineral-rich powder is 100% all-natural and as nourishing as it is stress-relieving. With a low alkali base, it shouldn’t throw your body’s pH, and also won’t stain your tub. Simply mix two tablespoons of the powder into a tub full of water and mix until it’s dissolved.
