<s>[INST]  Is eczema an allergic reaction? [/INST] For the most part, eczema is not caused by an allergy. With contact dermatitis, however, a child may have an allergy to the item or substance that comes in contact with the skin. Instead of an allergen, the item causing the irritation, which turns into a rash is known as a “trigger.” Avoiding these triggers (such as dust, perfumes, soaps and materials) is a key step to decreasing eczema flare-ups.
