Prevention: 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. There is no need for irritating soap. Sulfur soap is good for acne. Do not use oily cosmetics such as vanishing cream.

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

Taboo: Don't squeeze acne by hand, so as not to cause suppuration and inflammation, and the abscess will form scars and pigmentation after absorption.

Treatment: retinoic acid, viaminate, vitamin A, etc. It can improve the keratinization process and help to relieve and eliminate acne. If the above treatment methods are too troublesome, you can also go to a regular beauty and plastic surgery institution for color light acne treatment.
