Though most cases of dry skin (xerosis) are caused by environmental exposures, certain diseases also can significantly alter the function and appearance of your skin. Potential causes of dry skin include weather, air conditioning and central heaters, harsh detergents, sun exposure, and conditions such as atopic dermatitis and hypothyroidism. When left untreated, skin can become irritated, inflamed and itchy – properly termed eczema. Your physician can evaluate your dryness and recommend a treatment plan.
