Most cases of linear moss heal spontaneously after a few months, and no special treatment is needed. Topical glucocorticoid preparations or retinoids can help the lesions to subside. Linear moss is an inflammatory disease characterized by a linear arrangement of small polygonal papules, mostly on the limbs, trunk or face, progressing rapidly, with no conscious symptoms and occasional itching. Glucocorticoid ointments such as hydrocortisone butyrate ointment, or retinoid ointments such as retinoic acid ointment can be used for topical application, which can help the lesions to subside. Patients with linear moss of the skin are advised to go to the hospital in time for professional treatment under the guidance of the doctor, and not to take medication without authorization to avoid adverse consequences.
