Acne vulgaris is a chronic inflammatory disease of the sebaceous glands of the hair follicles. It is characterized by acne, papules, pustules, nodules, cysts and scarring. It is often accompanied by seborrhea. It occurs mostly in adolescent men and women. The formation of acne: 1. Androgens: During puberty, the body produces too much androgens, causing the sebaceous glands to secrete excessively. 2. Abnormal keratinization of hair follicles and sebaceous ducts: Keratinization of hair follicles and sebaceous ducts leads to impaired sebum excretion and sebum retention, resulting in acne. 3, microbial action: Propionibacterium acnes in the hair follicle and acne can multiply, producing lipolytic enzymes, proteolytic enzymes and hyaluronic acid lipids. Lipolytic enzymes break down the triglycerides in sebum into free fatty acids. Free fatty acids, proteolytic enzymes and hyaluronic acid lipids stimulate the follicle funnel and acne sac wall, causing sponge-like deformation and even the formation of smile clefts. 4, inflammatory mediators and inflammation: the role of various inflammatory mediators and pathogenic factors, resulting in acne content through the smile cleft into the dermis caused by perifolliculitis, the formation of inflammatory papules or pustules, or even nodules, severe cases can form scars after healing. 5, genetics, diet, gastrointestinal dysfunction, menstruation, mechanical stimulation, cosmetics, etc. can also induce this disease. Combination of Chinese and Western medicine in the treatment of acne: The combination of Chinese and Western medicine is very effective in the treatment of acne. According to Chinese medicine, acne is caused by heat in the lungs and stomach, which can steam up the face, or by external invasion of wind-heat, or by a diet that is too spicy, fatty or sweet, or by damp heat in the spleen and stomach. The heat and toxicity become toxic and overflow on the surface of the muscle. Chinese medicine treatment is based on the identification and treatment of symptoms, combining internal and external regulation to unblock qi and blood, clear heat and detoxify the body. This medicine has the ability to reduce sebaceous gland tissue, inhibit sebaceous gland activity, reduce cortical secretion, reduce epithelial cell keratinization and keratin plugging at the mouth of hair follicle sebaceous glands, and inhibit the growth and reproduction of Propionibacterium acnes. The dosage of medication is used according to the condition, and very satisfactory treatment results have been achieved. What should be noted in the diet of acne? 1. Avoid spicy and stimulating products: such as cigarettes, wine, strong tea, coffee, chili, garlic, leeks, dog meat, bird meat, etc. 2, avoid eating fishy food, avoid eating fatty, sweet and thick taste. 3.It is advisable to eat foods rich in vitamin A and B: such as green cauliflower, carrots, animal liver, etc. 4.It is advisable to eat cool and heat-eliminating foods: such as duck, mushrooms, fungus, celery, rape, bitter melon, loofah, winter melon, etc.
