Are soap-based facial cleansers really bad? How often should I use soap-based facial cleansers?

I have read a lot of skin care tutorials online, and they always say that soap-based facial cleansers are too powerful in cleaning. But are soap-based facial cleansers really that bad? Then why are there still so many businesses producing and selling them?

Are soap-based facial cleansers really that bad?

Of course, we cannot generalize whether soap-based facial cleansers are good or bad. Soap bases have their advantages, and amino acids have their benefits. We cannot generalize. Amino acids are relatively mild, but their cleansing power is not strong enough. Soap-based cleansing power is strong enough and is no problem for people with insensitive skin, oily skin, or combination skin. People with sensitive skin may need to cleanse with soap occasionally. Many big brands also use soap bases, but they are not very irritating, including La Roche-Posay, a specialized cosmeceuticals, which also use large soap bases.

The disadvantage of soap-based facial cleansers is that they have too strong a cleaning power, which can easily lead to over-cleansing, causing the skin to become dry and sensitive.

Soap scum is easily produced when encountering hard water, which is not easy to clean.

Since the skin is weakly acidic and soap base is alkaline, it has a certain degree of irritation to the skin.

The advantages of soap-based facial cleansers are strong cleaning power and thorough cleaning.

The foam is rich, and the skin feels refreshed and transparent after washing.

The raw materials of soap base are relatively cheap, so many manufacturers prefer to use soap base.

How often should you use soap-based facial cleanser? Soap-based facial cleanser can be used once every three days or so. Since soap-based facial cleansers have strong cleansing ability, frequent use will damage the skin's stratum corneum and destroy the skin's nutrients. In severe cases, it may cause skin sensitivity. In daily life, try to choose facial cleansers with milder and less irritating ingredients, so as to protect the skin barrier from damage.
