Many people say that they like to wash their faces with cold water, which is better and fresher for pores. But people's faces are not only thin but also sensitive, and there are many tiny nerves and blood vessels, which are also very sensitive. If you often wash your face with cold water, the stimulation of low temperature on your face will easily cause skin problems and some nerve problems. Although it is not good to wash your face with cold water, it does not mean that it is good to wash your face with hot water.
