What it is
Epsom salt is a popular beauty product among Hollywood celebrities and international models. Magnesium sulfate, a mineral found in seawater, has a powerful warming effect, improving blood flow, relaxing muscles, and easing stiff shoulders and back pain. It also reduces swelling. Magnesium also aids kidney function. Epsom salt can be boiled in hot water. To use, add approximately 150g to 200g (3-4 tablespoons) of Epsom salt for every 150 liters of bathwater. This high-purity Epsom salt is made in Japan. It also contains ascorbic acid (vitamin C), which has the effect of removing chlorine and improving skin beauty.
