Foot patches are not an IQ tax, but there are many unscrupulous businesses on the market that over-exaggerate the efficacy of foot patches, causing some consumers to fail to achieve the desired results after using them, so there are foot patches. It's an IQ tax. Foot patches generally contain ingredients such as mugwort and ginger, which can absorb excess moisture in the body and help remove moisture from the body, thereby improving sleep and enhancing immunity.

The foot patch is advertised to remove moisture from the body, but it only absorbs moisture from the surface of the skin.

The air humidity in humid places is high. People who live in coastal cities will not be surprised if there are water droplets on the tile walls during the rainy season, because there is too much water vapor in the air. But a humid place does not mean that our body is moist.

The fixed water content of the human body is about 70%, and this water is not moisture. The water content in the body will not increase just because you are in a humid city, nor will it rise because you are in a dry city. , the water volume will decrease.

Someone said that the fixed water content of the body is 70%, why does the skin still feel very dry? That’s because whether the skin is dry or not is reflected in the outermost layer of the stratum corneum. The moisture content of the stratum corneum will change with changes in environmental humidity. The moisture content of the stratum corneum will be higher in humid places and the stratum corneum in dry places. The moisture content will be lower. Therefore, in northern cities, you often need to pay more attention to moisturizing, otherwise your skin will dry out and break out in severe cases. The feeling of dryness in southern cities is much lower than that in northern cities.
