Acne on the face may be caused by mites, but it may also be related to genetic factors, androgen activity, sebum overproduction, Propionibacterium acnes proliferation, and abnormal keratinization of hair follicle sebaceous ducts. If mites are found on the facial area, mite dermatitis will appear on both sides of the nose and the nasal area, and some people may have dilated capillaries. You can go to the hospital for a mite test to observe whether the skin is infected with mites through a high-powered microscope. If there is mite infection, it is recommended to take oral medication with topical medication under the guidance of a doctor, such as oral metronidazole tablets or ornidazole, with the application of metronidazole gel or sulfur ointment locally, and also with the use of hyaluronic acid gel to increase the skin barrier function and jointly kill mites, so as to achieve the purpose of removing acne. In addition, patients should eat a light diet in their daily life, avoid spicy and stimulating foods such as chili peppers, pay attention to facial cleanliness, and can use amino acid cleanser to wash their face.
