My baby back side skin is like in this picture from last 4 months.I hv consult skin specialist and applied Eumosone M as suggested but nothing change. what to do?

A. Siri then you can just cross check with your doctor again because without knowing a story exactly is the issue and gets very difficult to give you a correct suggestion on that so when you have already consulted the doctor I suggest go ahead with a for the check up and if it is required to get a test done then get a test and all done to figure out what could possibly be the issue
