My friends has dermatitis next to her nose for six years or so. The affected area is very red and sometimes it is a little itchy. Her symptoms are more severe in summer than in winter. Doctors diagnosed it as seborrheic dermatitis, but it has been unable to radical cure by using some external used medicine. Only the tacrolimus ointment has slightly effective of her symptoms by now, but the drug effect only lasts about a week.
Anyone could help?
