Foam is produced in the process of washing your face, and it is easy to stay on the skin surface. One of the main components of facial cleanser is surfactant, which can fully mix water and oil and produce a large number of tiny foams. These foams can adsorb dirt and grease on the skin surface, but they are not easy to be completely washed off because of their light weight. Therefore, even if you wipe hard, it is still difficult to clean all the bubbles.
Personal cleaning habits will also affect the cleaning effect of facial cleanser. Some people just rub the facial cleanser in surface washing, without fully massaging and cleaning every corner. Some people are too eager to rinse off the foam quickly, but have no patience to rinse it repeatedly with warm water until the foam is completely removed.
The hardness of water quality will also affect the cleaning effect of facial cleanser. Calcium and magnesium plasma in hard water will react with the surfactant in facial cleanser to form insoluble matter and attach to the skin. These substances may make the foam difficult to rinse off and make the skin feel airtight.
Choosing the right facial cleanser is also the key. Doctors often recommend the use of mild facial cleanser with good cleaning effect. These products usually contain mild surfactants, which can effectively remove dirt and grease without causing excessive irritation to the skin. There are also some high-quality facial cleansers that contain moisturizing ingredients, which can moisturize the skin while cleaning. Therefore, it is the key to choose a facial cleanser that suits your skin type and needs.
To sum up, washing your face with facial cleanser can not completely clean the foam on your face, which may be caused by foam staying on the skin surface, improper personal cleaning habits, hardness of water, improper selection of facial cleanser and so on. Therefore, in daily care, you can try to use mild facial cleanser with good cleaning effect, and pay attention to full massage and washing to ensure the cleanliness and comfort of facial skin.
