For most people, facial cleanser is an essential daily product. In recent years, most people have begun to pay attention to the safety of facial cleansers, and find the most suitable one for themselves. Then, the question of whether facial cleanser is acidic or alkaline has emerged. What does acidic or alkaline mean?

pH value testing obtained acidity and alkalinity

Many makeup experts will do pH value tests to measure whether this skincare product is suitable for our skin, in which H stands for hydroxide ion, and P stands for the activity of hydroxide ion. The accurate measurement standard of pH value is 0-14. Neutral solution is 7 (while the pH value of cold water is closest to 7), acidic when below 7, alkaline when above 7.

Body skin pH value

The normal skin surface is pH value of about 5.0~7.0, but due to individual differences, the skin can reach as low as 4.0 and as high as 9.6, with an average of 5.8. Therefore, in the normal pH environment of the skin, it is in a weak alkaline state, which is the best for skin nutrition absorption. In the normal pH environment, the skin can resist external corrosion and maintain luster, elasticity, and moisture, all of which are the best condition. Therefore, it can be seen that pH value is closely related to skincare.

Is the facial cleanser acidic or alkaline

According to the requirements of relevant laws and regulations, the pH value of facial cleansers should be between 4.5-8.5, which means that the acidity and alkalinity of facial cleansers are determined according to the products you choose. For example, if your skin has been in the pH range of 5.0-5.6 for a long time, it indicates that the alkaline buffering capacity of your skin is poor, and the skin will also change, causing skin aging and damage. Therefore, the facial cleanser you choose should be a product with a pH value maintained between 5.0-5.6 to improve the skin texture and make the skin look its best. In addition, the alkaline environment of the skin can inhibit the growth of harmful bacteria, protecting the skin from damage.

In addition, when using soap and applying alkaline skincare products, the skin is prone to inflammation or boils, especially for people with rough skin or excessive sweating, whose skin has low buffering capacity. Therefore, it is not suitable to use alkaline skincare products.

WashIs the acidity or alkalinity of the milk suitable for yourself

As mentioned above, according to national standards, the pH value of facial cleansers should be between 4.5-8.5, which means that the different acidity and alkalinity of facial cleansers are different. So, which type is suitable for me? In fact, acidic and alkaline facial cleansers are softer and more suitable for dry, mixed, and sensitive skin. On the other hand, alkaline facial cleansers have higher cleaning power and are more suitable for oily skin with excessive sebum metabolism. Therefore, when choosing a facial cleanser for yourself, you must pay attention to the acidity and alkalinity of the facial cleanser and find the most suitable one, which is the best choice.
