This is a bath salt made with 100% Dead Sea mineral salt, unscented and uncolored. Dead Sea salt is characterized by its exquisite balance of various minerals, centered around magnesium. Minerals moisturize your skin and help keep it healthy. Additionally, the bathing effect warms your body from the core. You can enjoy bathing in the unique Dead Sea minerals at home. At salons, using the foot bath before massages or treatments is also very popular because it warms the body. Also, when using scented salt, please use it if you want to increase the mineral concentration without changing the scent intensity. *The specifications for the 5kg container have been changed. *The 4kg refill is for a 5kg bucket. ■ How to Use Add 40 to 100g of water to about 160 to 300 liters, stir, and then take a bath. *Please use the amount that suits your skin condition and scent preferences, and if your skin is dry, start with a small amount. * After bathing, do not leave any leftover water unused; drain it promptly and rinse the bathtub and circulation filter.
