【Features of Epsom Salt Cosmetic Water】 Citric acid has been added to our conventional Sea Crystals. Citric acid is the sour component of citrus fruits and pickled plums. It prevents dry skin caused by chlorine and warms the body, absorbing magnesium from the skin to enhance the synthesis of acylceramide and restore the skin's barrier function. Cosmetic Water was developed with the aim of promoting mineral replenishment and achieving a weakly acidic pH through the use of citric acid. As this bath additive is for the purpose of beautifying your precious skin, we couldn't help but choose the highest quality. Sea Crystals uses raw materials that meet the Japanese food additive standards and is manufactured in our own factory that adheres to cosmetic manufacturing standards. Of course, it has also passed radiation testing, quasi-drug raw material inspection tests, and post-manufacturing inspection tests, so please use it with confidence. *A measuring spoon is included in each set.
