ABSTRACT
As the skin ages, its ability to produce and maintain the normal oils and fats that help retain moisture erodes. The skin becomes drier and moisturizer must be applied more often to avoid itchy, painful, or fissuring skin (6 see also 84). Xerosis (skin dryness) is usually worse in the winter due to low humidity and indoor heat. Xerosis may be a problem unto itself or it may worsen common skin conditions such as eczema or psoriasis. It can be particularly difficult for elderly patients to avoid, as bathing and applying moisturizer may be more difficult due to arthritis, visual problems, or other comorbid conditions.
