Wash your face with warm or cold water.

No matter spring, summer, autumn and winter, don't wash your face with hot water. Wash your face with warm water or cold water in all seasons. Because of its strong irritation, hot water has a serious negative impact on the original delicate skin.

Warm water and cold water are different. Warm water not only has a good cleaning effect, but also does not irritate the skin, especially cold water. Sticking to cleaning facial skin with cold water in summer can shrink pores very well and will not stimulate subcutaneous blood vessels.

It lays a solid foundation for future skin care, and don't forget to use a thin layer of isolation cream after cleaning the skin every time to ensure that the skin is not stimulated by the outside world.

Extended data:

As we all know, the stratum corneum is the first line of defense of the skin, which can resist external stimuli. In fact, the outer layer of everyone's skin is the stratum corneum, which protects the skin.

The stratum corneum ('stratum corneum' in Latin) is the outermost layer of epidermis, which is mainly composed of 10 ~ 20 layers of flat dead cells without nucleus. When these cells fall off, the cells located in the basal layer will be pushed upward to form a new stratum corneum.

After cuticle exfoliation or artificial exfoliation, the epidermis will rapidly proliferate keratinocytes, which will be transformed into dead seedless keratinocytes and transported to the skin surface. The whole process takes about 14 days.

Excessive removal of the stratum corneum will cause the stratum corneum to become very thin, the skin will be more sensitive, and serious red blood will appear.
