Using tweezers to pluck the beard may produce certain bad effects, which may lead to secondary infection, meningitis, folliculitis, boils and other conditions. 1. Secondary infection: If the tweezers are not thoroughly sterilized or the skin is scratched when plucking the beard, bacteria or germs invade, leading to secondary infection around the beard, redness, swelling and pain. 2. Meningitis: If you pull out the beard blindly, it may stimulate the cavernous sinus in the patient’s skull and induce meningitis, but the probability of this is relatively low. 3. Folliculitis: when pulling out the beard, it is very likely to cause the skin in the follicle area to be damaged, the germs invade and cause folliculitis, resulting in redness and swelling of the hair follicles of the patient, accompanied by obvious pain around the follicles, and the hair in the middle of the follicle has hair through. 4. Boils: related to Staphylococcus aureus infection, usually folliculitis is not controlled in time, the spread of inflammation may be formed, manifested in the appearance of small hard knots, hard knots accompanied by hot pain and other phenomena. You can not use tweezers to pull out the beard indiscriminately, so as to avoid abnormal reactions, if necessary, you can consult a doctor in a timely manner, under the guidance of a doctor to standardize the treatment.
