How to protect the skin?

First, clean the skin. Skin covers the surface of human body, keeping out a large amount of invading bacterial dust. In addition, the skin itself is constantly metabolized, and12 million epidermal cells fall off every day. Therefore, cleaning the skin frequently is the most basic way to protect the skin. Conditional students take a bath for 5- 10 minutes every day, which can wash away the sweat and dust on the skin surface. Face is the most exposed part of human skin and needs cleaning. Wash your face three times a day, use cold water in the morning and evening, and thoroughly clean dust and grease with warm water and facial cleanser or soap before going to bed. People with acne should wash their faces with warm water, because warm water can dissolve sebum.

Second, pay attention to diet and nutrition. A person's skin is like a mirror, reflecting the health and nutrition in the body, especially the facial skin is extremely sensitive to nutrients. Once a certain nutrition is lacking, it will show symptoms. If protein and fat are lacking, the skin will become rough and gray; Without vitamin A, the face will swell and the mouth will fester. It can be seen that diet is closely related to skin fitness. Teenagers should not develop the habit of partial eclipse, but should determine a reasonable nutritional structure according to their skin quality. For example, students with oily skin can eat more vegetables, fruits and other foods containing a lot of vitamins. People with dry skin can eat a proper amount of high-fat food to keep their skin shiny. In addition, always drink water and take good care of your skin. Drink 4-6 cups of boiled water every day to keep your skin moist and shiny.

Third, use skin care products correctly. The sebaceous glands of teenagers' skin are exuberant, so you should use less skin care products. If you need to use it, you must carefully choose skin care products suitable for your skin. For example, people with dry skin can choose facial cleanser rich in oil, and after washing their faces, apply a layer of oil-rich nutritional emulsion. Gently massage can moisturize the skin and prevent dryness; People with oily skin can choose cleansing cream to wash their face, and use scrub once every two or three days to thoroughly remove dirt and sebum in pores, remove cuticle, and apply shrinking water after washing your face to promote pore contraction and smooth skin. In addition, when using skin care products for the first time, carefully observe the skin reaction to determine whether to continue using them. Proper use of skin care products will make the skin icing on the cake and more attractive.

Fourth, get enough sleep. Some students have the habit of staying up late, sleeping less than 8 hours a day. Lack of sleep can cause listlessness, flabby skin, haggard face, black eyes and other symptoms.
