Foot patches cannot remove moisture.
The dehumidification and detoxification effects of foot patches are often over-exaggerated by merchants. It is claimed that the foot patch can absorb toxins retained in human body cells and effectively remove body toxins and moisture. After the foot patch is applied, the dark substance that appears on the soles of the feet is the adsorbed "toxins".
It is even promoted that foot patches can eliminate skin spots and acne, improve constipation, and eliminate bad breath and foot odor in a short period of time. Moreover, foot patches can also reduce blood pressure, blood lipids, and blood sugar, improve skin gloss, improve sleep, and delay aging.
Extended information:
The dark "toxins" on the foot patches may be just a "concealment trick" by the merchants. As long as you put a few drops of water on the foot patch, the foot patch will turn black. Therefore, the blackening of the foot patch is not due to detoxification, but because it is soaked with sweat.
Whether it is the residue after digestion of food or the waste produced by human body metabolism, the human body mainly excretes "waste" through feces, urine, breathing, sweat, and hair, and the soles of the feet are not the main route.
