To prevent and treat acne, we should pay attention to the following points: 1, and it is best not to turn your face into a test base for chemical products. All products contain chemical products, otherwise the shelf life will not be so long, but they just don't want to admit it! Most people wash their faces once in the morning, lunch break and before going to bed at night, but people with greasy skin, greasy working environment, high ambient temperature or regular exercise, especially athletes, should increase the frequency of washing their faces. Wash your face in time after exercise or going out to go home, wash away the dirty dust and grease on your face, keep your face clean and dry, and avoid dirt blocking your pores. The effect of washing your face is that your appearance is dull. As for cosmetics, if people with oily skin choose oily cosmetics, it is undoubtedly worse, which is easy to block pores and produce acne and acne. Therefore, people with oily skin are suitable to choose cosmetics or skin care products in the form of dilute milk, remove makeup every day, and clean with neutral facial cleanser and facial cleanser with strong degreasing ability at least twice a day. After washing your face, you can wipe it with astringent water or refreshing soft water, and use an exfoliating cleansing mask once a week to clean pores. 3. People with oily skin should not only wash their faces frequently, but also wash their hair frequently, because the oiliness of the scalp can easily lead to acne at the junction of hair and face. 4. Sebaceous glands secrete oily skin and avoid massage, so as not to stimulate oil secretion, which is more likely to cause acne. 5. It is best not to have long hair, or spread it on your face, which is easy to irritate your skin and cause acne. 6. Don't touch your face with your hands, because your hands are not only easy to carry bacteria, but also stimulate unnecessary acne because of the touch of things. Don't squeeze acne by hand, so as to avoid festering and inflammation. After the abscess breaks, it will form scars and pigmentation, which will affect the appearance. The skin and finger instruments are not disinfected, the technology is unprofessional, and the judgment on the degree of acne is incorrect. Squeezing acne easily hurts the dermis, leaving pits (permanent) and spots that are lifelong regrets. 7. Pay attention to sun protection when you have acne on your face, and try not to bask in the sun. Some people think that painting your face black can cover up the red spots on your face. In fact, not only can't cover them up, but it has the opposite effect, which is to make acne more serious. For example, swimming at the seaside is not only strong in ultraviolet rays, but also very irritating to skin that is prone to acne. 8. If you have acne on your face, you should avoid using foundation and cosmetics. Some people try to cover it up with foundation, which backfires. 9. Keep a happy mood and get enough sleep to avoid the rise of liver fire and cause hormonal imbalance. In addition, get into the habit of getting up early and defecating every day, exercise more, work and rest normally, or drink more yogurt to change the ecology in which bacteria are easy to breed in the intestine. 10. Try to have a light diet, drink more water, eat more fruits and vegetables, less oil, less sweetness and less irritation, and avoid eating too many foods containing pigments and artificial flavors, as well as foods containing caffeine. Strong tea, coffee, cocoa, chocolate and so on. It is also easy to stimulate oil and endocrine disorders and form more serious acne. In addition, don't drink too much, smoke, and take supplements at will, because many traditional Chinese medicines commonly used by women to regulate menstruation, such as astragalus, cassia twig, cinnamon, medlar or Siwu decoction, Siwu pill, etc., are also easy to induce acne. 1 1. People who are prone to acne on their mouths should pay attention to the use of toothpaste, because fluoride in toothpaste can easily induce acne. You can choose fluoride-free toothpaste, or you must clean the toothpaste left on your mouth after brushing your teeth. 12. Never neglect the cleaning of pillow towels and pillowcases. Change the pillow towel once every two days and the pillowcase once a week. Pillow towels often come into contact with facial skin. If you just wash your face without changing the pillow towel, it is equal to not washing your face. Because the pillowcase directly touches the face, it is easy to get dirty things such as mites, dust and dandruff, so it should be replaced regularly.
