My baby has rashes on his face and we applied calamine lotion after consulting local doctor but it doesn't goes off and still looks like increasing. Please help

A. If It is still increasing that means it is some kind of an allergy and is quite good to deal with a rash issues so as of now would advise you to consult a skin doctor would be able to guide you with the right medicine for this so yes a skin doctor would be a better person to contact
