Facial cleanser containing soap base may destroy the natural protective barrier of skin. There is a lipid barrier on the skin surface, which can maintain the water-oil balance of the skin and resist external pollution and irritants. Soap-based facial cleanser has strong cleaning ability, and it is easy to remove oil and dirt on the skin, but it is also easy to remove natural oil on the skin surface. Long-term use of soap-based facial cleanser may make the skin dry, rough and even allergic.
Soap-based facial cleanser may destroy the acid-base balance of skin. The surface of human skin is in a weak acidic environment (pH value is about 5.5), which helps to keep skin healthy. However, facial cleanser containing soap base is often very alkaline. Excessive use or long-term use may destroy the acid-base balance of the skin, make the skin dry and sensitive, vulnerable to bacteria and viruses, and lead to various skin problems.
Facial cleanser containing soap base may damage skin barrier function. There is a stratum corneum on the skin surface, which is the protective barrier of the skin and can prevent water loss and the invasion of external stimuli. Too frequent or long-term use of soap-based facial cleanser may make the stratum corneum thinner and weaken its protective function. In this way, the skin is easily stimulated by the outside world, leading to problems such as sensitivity, redness and swelling.
Soap-based facial cleanser may have adverse effects on oily skin. Oily skin itself will secrete more oil, and the use of soap-based facial cleanser will further remove the oil on the skin surface, leading to more exuberant oil secretion. In this way, oily skin is prone to problems such as luster and acne. Therefore, for people with oily skin, long-term use of soap-based facial cleanser may not be appropriate.
