Mites on the face usually refer to worm mites, which are normal parasites that exist in human skin. Depending on the number, the immunity of the body and lifestyle habits, the reaction varies. There are usually a small number of mites on the face, which usually do not cause lesions, but when there are more mites, there will be corresponding symptoms, such as acne and folliculitis. If you are worried about your facial mite situation, you can go to a regular hospital for examination. Mites generally need to be examined through a microscope, and tissues are obtained by the transparent tape paste method, squeeze and scrape smear method or squeeze and bond method at the examination site, and professional doctors will observe and diagnose through a microscope. Mites are commonly found in the skin and are less pathogenic, so no special treatment is usually needed and there is no need to worry too much if they do not cause the corresponding symptoms. In daily life, you should practice good hygiene and eating habits, and change and disinfect bed sheets, pillowcases and towels regularly. Do not share household items, towels, washbasins, etc. with others. Eating less sweets, fried foods, greasy and spicy stimulating foods such as cakes, fatty meats and chili peppers, eating a light diet, eating more vegetables and fruits and drinking more water can all play a role in preventing excessive mite growth. Those who have more facial mites and more serious symptoms can use warm water, sulfur soap to clean the face under the guidance of a professional doctor, apply sulfur ointment and metronidazole ointment locally, and also take anti-inflammatory drugs such as metronidazole tablets or doxycycline hydrochloride tablets orally to relieve local inflammatory reactions such as redness, swelling and itching under the guidance of a doctor.
