1) Pay attention to facial cleaning: wash your face with warm water, because cold water is not easy to remove oil, and hot water promotes sebum secretion. No need for irritating soap. Sulfur soap is good for acne. Do not use oily cosmetics such as vanishing cream.

2) Reasonable diet: eat more fruits and vegetables, and eat less irritating foods such as fat, sugar and spicy food to keep the stool unobstructed.

3) Don't squeeze the acne by hand, so as to avoid festering and inflammation. After the abscess is absorbed, it will form scars and pigmentation, which will affect the appearance. Antibiotics are effective for serious infections.

4) Treatment: Use retinoic acid, vitamin A, etc. It can improve the keratinization process and help to relieve and eliminate acne. Benzoyl peroxide has obvious curative effect on acne. After being coated on the surface of human body, it can slowly release oxygen and has obvious bactericidal effect. Take 0.5 ~ 1% zinc sulfate solution, 30ml each time, three times a day. The general dosage is 4 ~ 8.
