Very Dry Skin Problems, Eczema. Is the a Cure for This?

I have a very dry and sensitive skin. I have eczema sometimes on my hand or on the top of my feet. I used 'Diprogenta Cream 15g' the doctor told me to first apply warm water on the eczema after that apply the cream every morning and night until the eczema is gone. I did as he asked and it work but it came back after a couple of month.I had it when I was around 6 or 10 years old. Some doctors told me as I grow up it will go eventually and when I'm 18 I will not have this eczema. I just turned 18
