Acne on the body may be caused by chronic inflammation of the hair follicle sebaceous glands due to hyperkeratosis of the skin, or chronic inflammation of the sebaceous glands due to impaired sebum excretion, or endocrine disorders caused by staying up late or getting angry. To treat acne on the body, first of all, avoid emotional excitement or excessive psychological stress, ensure sufficient sleep, preferably before 11 pm; do not eat stimulating, spicy food, less sweets, fried and barbecued food; drink more water, eat more fresh vegetables and fruits, and do not smoke or drink alcohol. In addition, pay attention to skin hygiene, avoid squeezing the acne area with your hands, and wash often with warm water or neutral bathing lotion and soap, which can effectively relieve oily skin. If you do not get relief for a long time, it is recommended to go to the hospital for further examination and treatment under the guidance of a doctor.
