How Is Atopic Eczema Treated? continued...
Other drugs that might be used for patients with eczema include antibiotics (to treat infected skin) and antihistamines (to help control itching).
Phototherapy is another treatment that helps some people with eczema. The ultraviolet light waves found in sunlight have been shown to benefit certain skin disorders, including eczema. Phototherapy uses ultraviolet light, either ultraviolet A (UVA) or ultraviolet B (UVB), from special lamps to treat people with severe eczema.
Risks associated with phototherapy include burning (usually resembling a mild sunburn), dry skin, itchy skin, freckling, and possible premature aging of the skin. Your health care professionals will work with you to minimize any risks.

What Are the Symptoms of Granuloma Annulare?
People who have granuloma annulare usually notice a ring of small, firm bumps over the backs of the forearms, hands, or feet. More than one ring may be noticed in some cases. The rash may be mildly itchy.

Lichen Planus and Your Skin
Lichen planus is a common skin disorder that produces shiny, flat-topped bumps that often have an angular shape and a reddish-purplish color. Lichen planus can occur anywhere on the skin but is often found on the insides of the wrists and ankles, the lower legs, the back, and the neck.
