Reasons for skin rubbing mud

Sometimes the skin may become rubbed into mud. There are many reasons why the skin may become rubbed into mud. Cosmetics combine with dirt in the pores, which will cause the skin to become rubbed into mud after rubbing, forming strip-like marks on the face. The mud-rubbing phenomenon is sometimes related to the quality of cosmetics. It may be because the quality of the cosmetics is not very good and the skin absorbs it poorly, so this phenomenon occurs. Let’s take a closer look at the reasons why skin rubs mud.

1. Natural organic polymer compounds (such as cellulose, protein, silk, rubber, starch, etc.), whose relative molecular mass can range from tens of thousands to millions or even larger, are often composed of countless small structural units arranged in a repetitive manner. They can break down under certain circumstances, producing segregation variation. Therefore: A) Gel products are most likely to cause mud rubbing. Since Carbohydrate (a material for making gel products) is a type of high molecular polymer, the products made from it are likely to become muddy. B) Skin care products containing protein may cause muddying, such as skin care creams with added collagen, etc.

2. Old skin and thick stratum corneum. In dry weather, the skin will produce more dandruff. When applying skin care products, the dandruff mixes with the skin care products to form "mud" - this is possible, but it depends on the specific situation

3. Incorrect usage: After applying foundation, you find your skin is dry, so you apply multiple layers of skin care products on top. So the powder on the skin is rubbed into "mud" - this may happen

4. Skin care products from different emulsification systems may react with each other and cause rubbing into mud. For example, some water containing glycerin will cause mud to form when used with certain skin care products. So JMS had been using a certain cream without any problems, but suddenly changed to a watery one and applied it before the cream, and then it started to rub into mud. This is perfectly normal, haha.

5. Some people believe that the phenomenon of rubbing into mud is caused by the incompatibility of oil and water in cosmetics. If you use an oil-soluble base under your cream and your frost is water-soluble, it will definitely become muddy. In addition, cosmetics are divided into hydrophilic and lipophilic. If you use lipophilic products on hydrophilic skin, it will basically turn into mud. --This is possible.

6. Some people think that it is caused by poor absorption and all the makeup floats on the face. It is very likely that this product is not suitable for your skin type. Try another one. If none of them works, it is recommended to use a primer or some primer that is specifically designed to enhance absorption. This possibility is relatively small.

7. Sunscreen isolation cream usually contains titanium dioxide or titanium dioxide aqueous solution, which is not very compatible with oil and easily forms "mud" or white flakes when rubbed

8. Some people think that because the weather is cold, the emulsifier becomes thicker, and the thick emulsifier will cause mud - this is impossible and purely imaginary. 9. Usage method: After applying moisturizing gel or essence containing polymer glue and water-soluble thickener, immediately apply foundation or sunscreen containing metal ion ingredients such as titanium dioxide and zinc oxide, which will produce salts, which are the white crumbs we see with the naked eye;
