Hi Doctor

I have a skin irritation in the creases under my nose leading down to the outside of my lips. I have been given a Canestan cream by the doctor and I have used this for 2 weeks. The itchiness which is very red and sometimes spotty completely disappeared until I stopped using the cream and now it is starting to become itchy again and is slowly coming back. I don't want to use steroid cream anymore as it's not wise to use this on my face. What else can I use? Should I ask the doctor for a course of antibiotics, or someone has suggested I try using the gel from an aloe vera plant. Can you help and advise please?
