The first step of skin cleaning is to wash your face twice a day in the morning and evening. In addition to special facial cleanser and soap, some people wash their faces with soap. How about soap?
First of all, let's understand the ingredients of soap. Soap is generally divided into weak acid soap and weak base soap, and its main component is sodium fatty acid. Most soap is made of animal and vegetable oil saponification, which will not have side effects on human body, and it is also easy to be explained by the environment, environmental protection and non-toxic, which is very desirable.
The benefits of soap washing
1. Soap has good cleaning effect
Now a lot of facial cleansers only focus on skin care ingredients, the cleaning ability is not as strong as soap, so the effect of soap is OK. Some people may worry that soap alkalinity will damage the skin, but in fact, some acid dirt like horniness and dust will adhere to the surface of normal skin. Using weak alkaline soap to clean it is just right, and it can also keep the skin shiny.
2. Soap can resist oxidation
The old waste horniness, grease, dust and other acid dirt on the surface of the skin are easy to block the pores, especially in summer, or oily skin, which is more obvious. Wash your face with a weak alkaline soap, which can help clear pores and prevent skin from oxidation and aging.
3. Soap can exfoliate
Alkaline soap will react with acid cutin. When you wash your face with soap, the cutin will be softened slowly, so that the skin will become shiny. To wash your face with soap, you need to blister your hands first and then apply them to your face. Finally, you should pay attention to rinsing the foam with clean water, especially the hair line and ear hair position, otherwise it will be easy to grow smallpox.
Finally, it should be noted that although soap is good for face washing, it is not recommended to use it for a long time. In addition, weak acid soap should be chosen as far as possible. Because the alkaline soap will make the skin dry, long-term use, or will cause skin cuticle thinning, skin allergy and other symptoms, especially for sensitive skin, more attention should be paid. After washing face with soap, make sure to moisturize the skin to prevent dry skin.
