If the condition of your skin problem is chronic and nothing you have done relieved you of it then you definitely must see a doctor, a dermatologist will be better. Meanwhile take a look at this website: http://www.webmd.com/skin-problems-and-treatments/guide/atopic-dermatitis-eczema. Also avoid fatty foods and sugary foods, too. Don't expose yourself to too much sunlight and avoid dusty humid places. Wash your face with plain soap and water before going to bed at night.
I have excema on my hands and bends of my arms. I had to go to a dermatologist and she prescribed me this thick medicated lotion and within a day of using it, my excema was clear.I would suggest going to a dermatologist.
