It is certain that your feet will sweat. Eccrine glands mainly secrete water, salt, potassium, calcium, urea, lactic acid and amino acids, while apocrine glands mainly secrete water, iron, fat, fluorescent substances and odor substances. The normal detoxification and excretion is defecation, and the skin discharges a lot of toxins, just like our face will discharge oil. When there are some chemical inorganic substances in our body, they become toxins, especially.
The foot bath detoxifier is real, but it can't attribute the color of the whole basin of water to the body. After all, some of them are produced when the machine works. To know that the oil floating on the water is excreted by the body, we can also see many cases of beriberi patients seeking medical treatment quickly. Anyway, it helps solve their own problems, that is, it is effective, but it is not medical equipment.
