Pathogenesis and treatment of seborrheic dermatitis
Seborrheic dermatitis is a chronic,recurrent,and inflammatory skin disease.Its etiology is intricately related to skin microecological imbalance,dysregulated lipid metabolism,impaired skin barrier function,abnormal immune responses,and genetic predispositions.In recent years,several novel therapeutic approaches have emerged,such as topical phosphodiesterase 4 inhibitors,Janus kinase inhibitors,physical interventions,and chemical peeling,providing more options for the treatment of seborrheic dermatitis.This review summarizes the latest research progress in the pathogenesis and treatment of seborrheic dermatitis.
