2. Exposure to Certain Metals
One of the more common reasons for developing dyshidrotic eczema is an adverse skin reaction to certain metals. Both nickel and cobalt are known agitators of the condition. Medical science is at a loss to understand why the skin produces this reaction to these metals, but some medical experts believe that it occurs due to an allergy effect.
People who wear jewelry featuring these metals may find that they develop symptoms of dyshidrotic eczema. If the affected individual wears a bracelet or wristwatch made from nickel or cobalt, then they are likely to incur blisters on their hands.
Dyshidrotic eczema can occur at any stage of life. Some patients may find that they had no previous allergenic response to these metals, but they start to exhibit symptoms of dyshidrotic eczema later in life. If this is the case, then the affected person should evaluate their jewelry, and avoid wearing any pieces that contain cobalt or nickel.
