What causes rosacea?

For many people, their noses suffer from varying degrees of rosacea symptoms, which directly affects a person's appearance. There are many causes of rosacea at present, such as: sebum secretion, repeated infection of Demodex, improper eating habits, endocrine disorders, digestive dysfunction, etc. Therefore, in addition to certain drug treatments, you should pay attention to your diet in your life and avoid spicy and irritating foods and smoking and drinking.

Rosacea, also known as rosacea, is a chronic inflammatory skin disease characterized by erythema and telangiectasia that occurs primarily in the central part of the face. It is more common in middle-aged people aged 30 to 50, especially in women.

The cause is not yet fully understood. It may be due to the action of various harmful factors inside and outside the body on the basis of sebum secretion, which causes the vasomotor nerve dysfunction and long-term dilation of capillaries in the affected area. Trichocystis and repeated local infection are important factors for the onset of the disease. Alcoholism, smoking, spicy diet, gastrointestinal dysfunction, endocrine dysfunction (especially during menopause), mental factors, lesion infection, and long-term exposure to hot and cold factors on the skin such as high-temperature work, sun exposure, cold, wind, etc. can all induce and aggravate this disease.

The disease is prone to occur in the middle part of the face, mainly on the tip of the nose and the wings of the nose, followed by the cheeks, chin, and forehead. It is often distributed symmetrically and is more common in middle-aged people, especially women. Patients often have seborrhea, and their faces look like they are covered with fat. Skin lesions manifest as erythema, telangiectasia, and inflamed follicular papules and pustules. The disease progresses slowly and can be divided into three stages without clear boundaries. It is divided into 3 stages: erythema stage, papule stage, and hypertrophic stage.

The diagnosis can be made based on the presence of congested erythema and telangiectasia in the middle part of the face, a chronic course, no obvious symptoms, onset in middle age, and recurrent papules and pustules.
