Irritant contact dermatitis is caused when a harsh substance aggravates the skin by repeatedly contacting it.

In this case, the irritant is the water that is drying out and damaging the skin with repeated exposure.

Nummular dermatitis consists of distinctive coin-shaped red plaques that are most commonly seen on the legs, hands, arms, and torso. It is more common in men than in women, and the peak age of onset is between 55 and 65. Living in a dry environment or taking frequent very hot showers can cause this condition.

Atopic dermatitis, or eczema, causes the skin to itch, scale, swell, and sometimes blister. This type of eczema usually runs in families and is often associated with allergies, asthma, and stress. Defects in the skin barrier, allowing moisture out and germs in, may also come into play.
