Why can't scabies mites be transmitted to the face?

The reasons why scabies mites usually do not spread to the face are as follows: The rarity of scabies mites spreading to the face results from the combined effects of facial skin conditions, personal hygiene habits, and immune function. 1. Facial skin characteristics: Facial skin tends to be more delicate and has more active sebaceous glands. Scabies mites, as parasites, require certain humidity and fat for survival, but the high-sebum environment of facial skin may not be conducive to the parasitism and reproduction of scabies mites. 2. Personal hygiene habits: People generally pay more attention to facial cleanliness and hygiene, frequently washing their face and using facial cleansers. These behaviors help reduce the risk of scabies mite infestation on the face. 3. Immune function: The immune system of the facial skin is relatively active and can effectively resist invasion by foreign pathogens, including scabies mites.
