The appearance of blackheads in students is usually due to the accumulation of sebum at the mouth of the hair follicles during puberty when the sebaceous glands are in full secretion. If the number of blackheads is small, there is usually no need to remove them as a normal physiological phenomenon; if you are more concerned or have too many blackheads, you can remove them through daily conditioning and medication. 1. Daily conditioning: Patients need to avoid squeezing with their hands to avoid infection and aggravate the symptoms, and pay attention to the regularity of work and rest. The skin can be properly cleaned with milder cleansers and skin care products, which can improve the accumulation of cortex at the mouth of the hair follicle to a certain extent and help remove blackheads and pimples. In addition, you should also pay attention to your diet, which should be light and avoid eating greasy, spicy and irritating foods, such as fried things, chili, hot pot, onion, ginger, etc., so as not to produce stimulation and aggravate the symptoms. 2, medication: under the guidance of a professional doctor, topical treatment can be carried out with drugs such as vitamin A acid cream and adapalene gel. If there is an infection, antibiotic drugs such as cefixime and amoxicillin can also be taken to help relieve the symptoms. Because of the tender skin of students, physical therapy such as laser treatment should be avoided as much as possible to avoid greater irritation.
