Hi doctor, I had a lot of red itchy and painful blisters on my face, especially on forehead near eyebrows and on both cheeks. I started using lobate gn cream, initially i got very good result, and my face became very clear and fairer looking, but again suddenly I am seeing those are coming back and started feeling same itching sensation, now what's to be done please advise, any medicine or treatment procedure can you suggest?
