"Urutsuya Carbonated Spring" is the industry's first powder-type bicarbonate ion bath salt. The neutral water, which dissolves quickly in hot water and is like a serum in which bicarbonate ions and beauty moisturizing ingredients are dissolved, leads to moisturized and glossy skin with a surprising experience that envelops the whole body. It is a whole-body serum bath salt that makes bath time, which is also a moment of peace, a more fulfilling time. * No coloring slight fragrance (faint scent of aqua soap) If you are a general household, please put one bag (30g) in a bath filled with hot water (a little lukewarm water is ideal) and take a bath. The concentration of bicarbonate ions does not decrease much over time, and you can fully enjoy it even if it is recooked.
