Rosacea is the medical term for rosacea, which can be caused by heredity, neurovascular dysfunction, skin barrier damage, diet and other factors. 1. Heredity: Rosacea runs in families. If a parent suffers from rosacea, it can lead to an increased risk of the disease in their children. 2. Neurovascular dysfunction: Prolonged inflammatory stimulation and changes in hormone levels may lead to neurovascular dysfunction, which may cause blood vessels to dilate and proliferate, thus triggering the disease. 3. Skin barrier damage: If you use incorrect skin care products for a long time, it may reduce the sebum content and lead to skin barrier damage, which will increase the chance of suffering from Rosacea. 4. Diet: If you consume high-calorie, high-fat and spicy food for a long time, or often drink alcohol or excitement drinks, it may also trigger the disease. There are many causes of rosacea, so it is recommended that patients go to a regular hospital for a checkup to determine the cause of the disease and follow the doctor’s instructions for treatment.
