you can't just use hydrocortisone. you need creams (Aquaphor or catephil), all the time! the key to avoid eczema is to keep the skin moisturized (not with water, but creams). I wish I knew this last year. you need to make sure your room humidity is not too dry, and avoid washing face/skin too often. use hydrocortisone and Aquaphor/catephil if the eczema is severe. otherwise, just spread aquaphor as often as you can. the more the better.
