What causes skin care products to become lumpy?

Many women have encountered this situation, that is, after applying skin care products on their face, they will find that mud can be rubbed out on their face. This is a very bad phenomenon. There are many reasons behind this. For example, some people buy skin care products of poor quality, which are not absorbed by the skin after use, and then the skin care products will rub out mud. In addition, it may be due to incorrect use of skin care products, etc.

Reasons for skin care products to be rubbed into mud:

Too many layers of skin care products

Many fairies around us easily fall into this misunderstanding. They apply layer after layer of makeup on their faces, saying that it makes their skin more nourished. But it is really too naive. After applying so many layers, can the skin absorb all of it? Just like many fairies think that the thicker the essence, the better, but what they don’t know is that the thick texture is actually a thickener and has no nutritional value. Remember, the more layers you stack and the more products you mix, the more likely it is to get muddy.

How to solve the problem of skin care products rubbing into mud?

Too many macromolecular components or colloid components in the formula

Generally speaking, skin care products are prone to becoming mud. From the perspective of ingredients, the culprits are mostly polymers or gelatinous ingredients. Their relative molecular mass can range from tens of thousands to millions or even larger, and they are often composed of countless small structural units arranged in a repetitive manner. They can break down under certain circumstances, producing segregation variation.

① Gel products are most likely to cause mud rubbing. Since Carbohydrate (a material for making gel products) is a type of high molecular polymer, skin care products made from it are prone to rubbing into mud;

② Skin care products containing protein may cause rubbing into mud, such as skin care creams with added collagen.

Using skin care products in the wrong order

If the phenomenon of rubbing mud is caused by the ingredients of the product, you can choose not to use the product. If this phenomenon is caused by the order of using skin care products, then it is much easier to deal with. You can choose to adjust the correct order of use. For example, large-molecule hyaluronic acid is the ingredient that is most likely to rub into mud when combined with other substances during normal skin care and makeup (Peter Thomas Roth Hyaluronic Acid Moisturizing Serum, gel-textured creams, sunscreen and foundation are all prone to rubbing into mud, try it if you don’t believe it). If you encounter this kind of situation, you may want to change the order. First use skin care products with small molecules and thin texture, and then use skin care products with large molecules and thick texture. In this order, the mud-rubbing phenomenon may be avoided.

The wrong way to use skin care products

In the process of skin care, common mistakes are often incorrect usage methods. Xiaoyan has summarized the following three common mistakes for everyone today: ① After applying moisturizing cream, essence and other products containing polymer glue and water-soluble thickeners, immediately apply foundation or sunscreen products, which will produce salts, which are the white flakes seen by the naked eye;

② If you apply lotions, creams and other products containing hydrophilic emulsifiers, such as fatty acid salts, and then immediately apply foundation, moisturizing primer and other products containing metal ions, their ingredients will also be replaced from water-soluble to water-insoluble salts;

③ Apply L-C or anti-acne products, such as acid, salicylic acid, etc., and then apply isolation milk and other products containing zinc oxide powder, which can easily produce precipitation. Apply sunscreen after the skin care routine. If chemical precipitation is produced, it will affect the isolation effect of the sunscreen.
