sea crystal is the product of seawater and salt chemical industry, which is mainly produced by a series of processes such as evaporation, centrifugation and concentration of seawater or brine. It basically retains the main components of seawater and is concentrated seawater. Adding trace elements selectively can not only supplement some elements and compounds lost in the production process, but also make the whole product more practical. For example, adding selenium and molybdenum can not only promote the growth of aquatic animals, but also make them develop in a healthier, more nutritious and all-round direction. It has nothing to do with preservatives. So, just like salt, put on gloves and contact them. When they soak into your skin, the surface cells will lose water, so you feel tight. .
