The appearance of redness and peeling skin on both sides of the nose and nasolabial folds is usually a sign of seborrheic dermatitis. Seborrheic dermatitis, is a skin inflammation that occurs well in seborrheic areas, such as the face, ears, nasolabial folds, nose, forehead, and back. It is often associated with excessive sebum production, as well as microbial infections of the skin. For common treatment, weak glucocorticoids, such as hydrocortisone ointment or Denide ointment, can be used on the face in the early stages, but they should not be used for a long time. Topical fungal preparations, especially imidazole, can be used topically, and 80%-90% of patients will have significant improvement and better results, such as miconazole and ketoconazole ointment. Oral vitamin B is also effective, with significant itching, can be combined with antihistamine antipruritic drugs.
