The cause and mechanism of keratosis pilaris are not yet completely clear, but it is considered to be related to heredity, and there is no complete clinical treatment. If the symptoms are mild, generally no special treatment is needed. If the localized symptoms are severe, appropriate medication, phototherapy or surgery may be given. Keratosis pilaris with mild symptoms can be closely observed and generally does not cause serious health effects, but it will affect the appearance of the skin. For patients with mild symptoms, it is recommended to pay attention to diet and skin care, supplement vitamins to enhance the body’s resistance, and generally do not need special medication. If the symptoms are obvious, you can follow the doctor’s instructions to give vitamin A, vitamin A acid and other drugs for treatment, if accompanied by secondary infection, if necessary, with antibiotic drugs, such as fusidic acid, mupirocin ointment anti-infection treatment. Hypertrophic lesions can also be treated with physical therapy, such as laser and freezing, which can achieve long-term relief of the disease. Hypertrophic skin lesions can also be treated by surgery, such as dermabrasion, if no improvement can be achieved by the above means. Patients are advised to visit the dermatology department of the hospital in time and choose the appropriate treatment method under the guidance of the doctor.
