Hi there is a dry skin patch under my right eye and now i have random dry skin patches on my face and neck and right ear lobe. i have no idea why?

Such might be eczema: A primary care doctor or dermatologist can evaluate. To treat mild or moderate dry skin eczema, many people use hydrocortisone cream twice a day, for a week or two. It's cheap, found at most stores and works well. A daily moisturizing cream (Cetaphil, CeraVe, Eucerin, etc.) used 2-4 times a day helps to heal eczema and to prevent return of the rash. Most eczema patients try to avoid soaps.
