Is soap-based facial cleanser suitable for oily skin? How often should I use soap-based facial cleanser?

Although soap-based facial cleansers have been demonized by everyone, in fact, as long as the soap is not used frequently, it will not have any effect if used occasionally. So, are soap-based facial cleansers suitable for oily skin? Let’s take a look together.

Is soap-based facial cleanser suitable for oily skin?

Soap-based facial cleansers can be used for oily skin, but they should never be used every day. The soap base has a very strong cleaning power, and if used every day, even oily skin will be damaged. For oily skin and acne-prone skin, soap-based facial cleansers are more suitable. Just pay attention to the frequency of use, single dosage, and method of use.

The harm of soap-based facial cleansers

Alkaline ingredients can damage the skin

One of the raw materials of soap base is sodium hydroxide, which is an alkaline substance. The sebaceous glands and sweat glands secreted by our facial skin will form an invisible protective film on the skin. This film is slightly acidic and it mainly plays a role in sterilization and skin care. If you use an alkaline facial cleanser to wash your face, it will easily destroy the protective effect of the skin's barrier film.

Very stimulating

Because soap bases have strong bubble ability and cleaning power, they will damage the stratum corneum and a layer of natural barrier outside the stratum corneum. Therefore, many people feel their faces are tight and dry after washing their faces with soap-based facial cleansers.

Soap residue will form soap scum

Soap bases can easily react with calcium and magnesium ions in water to form soap scum, which can clog our pores and cause symptoms such as acne and blackheads.

The difference between soap-based facial cleansers and amino acid facial cleansers

The main difference between soap-based facial cleansers and amino acid facial cleansers lies in the ingredients. The main ingredients of soap-based facial cleansers are fatty acids and alkali substances. The main ingredient of amino acid facial cleanser is amino acid surfactant (sodium acyl amino acid).

How often should you use soap-based facial cleanser?

Soap-based facial cleansers should be used once or twice a week. Although soap-based facial cleansers have better cleaning power, they are also more irritating to the skin, so they should not be used frequently. For healthy skin or oily skin, use it twice a week at most; for sensitive skin, use it once a week.
