Although acne is also a symbol of youth, a face full of “pimples” does bring more trouble, many teenagers are more concerned about how to take good care of their skin, prevent acne, stay young and not “acne”. Individuals should pay attention to the following points in their daily lives: 1. Develop good habits: pay attention to personal hygiene, bathe regularly, change clothes regularly, keep the face and hands clean, so that facial sebum is discharged normally. Wash your face with warm water often, avoid using alkaline soap, and do not use cosmetics with more oil and irritation to avoid further filling of hair follicles and aggravation of acne. Do not squeeze, pinch, or pinch with your hands, as this can cause inflammatory bacteria to develop deeper on the one hand, and disfiguring scars on the other. After acne occurs, you should go to the hospital to see a dermatologist as soon as possible. You should follow the doctor’s instructions, take the medication and rub it in carefully, and insist on it. Do not buy your own drugs and use them at your own discretion. Topical medications containing hormones should never be used because one of the side effects of hormones is that they cause acne and can aggravate the condition of acne. It is best not to abuse cosmetics when you have acne. You should pay more attention to your life at work and not wear heavy make-up. 2, pay attention to diet: eat less high-fat, oily food to reduce the intake of oil, to light diet is appropriate. Eat less stimulating food such as chili, wine, onion, garlic, etc. These foods will stimulate the secretion of sebaceous glands. You should eat more vegetables, fruits and light foods. 3, pay attention to some drugs can make acne worse: including some androgen preparations and sebaceous steroid hormones. Other drugs include halogenated elements and phenytoin sodium. 4, maintain optimism: ensure adequate sleep: avoid emotional anxiety and tension, maintain an optimistic and happy mood, to recognize that acne is a temporary physiological phenomenon. Study and work should be combined with work and rest, not long-term mental tension, to ensure 7-8 hours of sleep every day. Keep your bowels open. 5.Rational skin care: Use skin care products that control oil secretion and moisturize.
