Is facial cleanser acidic or alkaline? A survey on acid and alkaline facial cleansers

For most people, facial cleansers are a necessity in life. In recent years, most people have begun to pay attention to the safety of facial cleansers and whether they are suitable for themselves. Then, the question of whether facial cleansers are acidic or alkaline has emerged. So what are acidic and alkaline? Will these two have certain harm to the skin?

pH test to get acidity and alkalinity

Many beauty experts will do pH test experiments to calculate whether this skin care product is suitable for our skin with a pH value close to our skin, where H represents hydrogen ions and P represents the energy of hydrogen ions. The pH value is measured on a scale of 0-15. A neutral solution has a pH of 7 (the pH of ordinary water is closest to 7), an acidic solution has a pH of less than 7, and an alkaline solution has a pH of greater than 7.

pH value of human skin

The pH value of normal skin surface is about 5.0~7.0, but it varies from person to person, sometimes the lowest is 4.0, and the highest is 9.6. The average value of skin is 5.8. Therefore, the normal pH value environment of skin is weak alkaline, so the skin is in the best state of nutrient absorption. Skin in a normal pH environment can resist external erosion and has luster, elasticity and moisture, all of which are in the best condition. Therefore, it can be seen that the Ph value is closely related to skin care and beauty.

Is facial cleanser acidic or alkaline?

According to relevant national regulations, the Ph value of facial cleansers should be between 4.5-8.5. This means that the acidity and alkalinity of the facial cleanser is determined by the product you choose. For example, if your skin has been at a Ph value outside of 5.0-5.6 for a long time, it means that the skin's comprehensive alkalinity ability is weak, and the skin will also change, which will lead to skin aging and damage. Therefore, the facial cleanser you choose should be one that maintains a pH value between 5.0-5.6, which will improve the skin and keep it in the best condition. In addition, the alkaline environment of the skin can inhibit the growth of harmful bacteria and protect the skin from damage.

Also, when using soap and applying alkaline cosmetics, the skin is prone to inflammation or sores, especially for people with rough skin or who sweat a lot. The skin's neutralizing ability is lower, and of course it is even less suitable for alkaline cosmetics.

Is acidic or alkaline facial cleanser more suitable for you?

It was mentioned above that according to national standards, the pH value of facial cleansers can be 4.5-8.5, which means that different facial cleansers have different acidity and alkalinity. So which type is suitable for me? In fact, acidic facial cleansers are milder and more suitable for dry, mixed, and sensitive skin. Weak alkaline facial cleansers have higher cleaning power and are more suitable for oily skin with excessive oil secretion. Therefore, when choosing a facial cleanser, you must pay attention to the acidity and alkalinity of the facial cleanser. It is best to find a suitable facial cleanser.
