It is ineffective to treat demodex infection with skin care products. At present, there is no satisfactory drug to kill the adults, larvae and eggs of folliculosis, and naturally there is no specific method to kill mites. In order to prevent the infection of demodex folliculorum, we should pay attention to develop good personal hygiene habits in our life, and don't share toiletries with others, such as towels and basins, to avoid mutual infection; It is found that there is the possibility of follicular keratosis (skin inflammation after follicular keratosis infection), which needs early treatment to prevent the inflammation from getting worse. Because there is no satisfactory drug to kill folliculitis, the result is that mites are not easy to kill, and the skin condition may be aggravated repeatedly. At present, we treat cysticercosis with some drugs that inhibit fat and have certain curative effect on cysticercosis, and often get satisfactory results. If the treatment method is recommended, benzyl benzoate plus sulfur emulsion or ointment, or metronidazole (also called metronidazole) can be taken orally or made into emulsion to treat the infection caused by human demodex, which also has good curative effect and their cost is very low. Human demodex is a permanent parasitic mite. We have made a sampling survey among some college students, and the results show that the positive rate of demodex is over 40%. However, these college students with worm infection do not show skin diseases, so the infection of folliculosis is not necessarily a terrible thing, and it is not necessary to kill folliculosis without skin diseases. This is the first suggestion. Secondly, when there are symptoms of hair follicle infection or some skin diseases, it is best to go to a regular dermatologist. Specialists will choose appropriate dosage forms of related drugs for treatment according to different symptoms, which can receive good curative effect. Third, cosmetics for treating mites will not be omnipotent. When this cosmetic is applied to the treatment of keratosis folliculi, if it is used in a dosage form that does not conform to this skin inflammation, it will be counterproductive and aggravate the symptoms. Finally, in life, don't share bathing utensils; Diet should be light, low in oil, fat and sugar, and drink little or no alcohol. Although there is a concept that the problem of mites is caused by excessive secretion of androgen, it has little to do with diet. However, no matter what the concept is, from the perspective of health and beauty, low-fat and low-sugar drinking is always beneficial to the body.
