Symptoms: Itchy, irritated skin on the insides of your elbows, backs of the knees, or on your hands and face. If you have a very flaky scalp, seborrheic dermatitis is likely to blame. It typically causes a greasy buildup of skin cells on your scalp and the T-zone on your face, especially around your eyebrows.
How to treat it: For atopic and contact dermatitis, use a fragrance-free moisturizer frequently, limit bathing and exposure to irritants. For seborrheic dermatitis wash with a gentle cleanser to remove oil and use a medicated shampoo. Cold compresses are sometimes prescribed to relieve itching. For severe cases, doctors typically prescribe a topical or oral steroid. A new class of drugs called topical immunomodulators is now also being used to reduce the immune response associated with eczema.
