This is a fragrance-free and uncolored bath salt made from 100% Dead Sea mineral salt. This is a flaky bath salt with a higher magnesium content than our regular Dead Sea bath salts. Magnesium is said to be the "king of minerals", but magnesium chloride in particular is easily absorbed through the skin and is also known for its moisturizing properties. It is also characterized by not 100% purified magnesium, but also other minerals from the Dead Sea. Easily replenish magnesium with daily bathing! In addition to other bath salts, it can also be used to increase magnesium levels. *650g comes with a measuring spoon. ■How to use Put 40-80g in about 160L to 300L of hot water and stir before bathing. *Please try the amount that suits you according to your skin condition and fragrance preferences, and for dry skin, add a small amount at first. *After bathing, do not leave any leftover hot water unattended, drain it as soon as possible, and wash the bathtub and circulation filter.
