Effective face washing is also related to water quality and water temperature. Generally speaking, water quality refers to hard water and soft water. Hard water, such as well water and water containing calcium salt, light salt and minerals, is not easy to foam because it contains minerals, so don't wash your face directly with hard water.

If the conditions are limited, you can boil the hard water for a few minutes to allow the minerals in the water to fully precipitate before using it. Soft water refers to water that does not contain or contains a small amount of calcium and magnesium salts, such as rainwater and tap water. Soft water is an ideal product for washing your face.

After selecting soft water, pay attention to the water temperature of face washing water. Generally, there are two kinds of water temperature for washing your face: one is warm water, that is, water of 40 to 42 degrees Celsius, which is not hot and too hot for washing your face. The other is cold water, that is, water below body temperature, but not too cold, such as ice water. Too cold water is not good for the skin.

Warm water, which we can also call hot water here, can dissolve sebum, relax skin, dilate blood vessels, open pores, promote the discharge of metabolites, and have strong skin cleaning ability. But if you wash your face with hot water, it will easily lead to too little sebum and dry skin. Cold water can make skin blood vessels contract and pores close.

At present, a popular method of washing face in beauty industry is to wash face alternately with hot and cold water. This method advocates using soap as little as possible or not, and using hot and cold water alternately. Wash it with hot water first For people with oily skin, the water temperature should be kept at about 42 degrees Celsius. For people with neutral skin and strong epidermal resistance, it is advisable to use 40-degree hot water with lower temperature.

For people with dry skin and allergies, it is best to use water of 37 degrees Celsius close to body temperature. After washing with hot water, wash it with cold water again. Alternate use of hot and cold water can activate blood circulation of skin and delay skin aging.
