Over the last three years or so, the outer part of my arms between my shoulder, and my elbow have become very dry with lots of tiny rash/scabs. It's a darker than my skin, and very rough. Nothing seems to be helping on a permanent basis. I've used several medicated ointments/creams, but they only help for a short time. It is very embarassing whenever I wear tops that are sleveless, and I'm very conscious of this condition. Because I'm light skin, it's even more obvious. Help, Please!
