In a study appearing in the January 2014 issue of the Journal of the American Academy of Dermatology, researchers tested 2,453 people and found that those who had atopic dermatitis, or eczema, were more likely than people without eczema to have an allergic reaction to certain ingredients in topical products. The reaction—allergic contact dermatitis—can result in a rash or red, itchy, swollen skin, sometimes with blisters.

Avoid skin-care products containing the following formaldehyde releasers: quaternium-15; imidazolidinyl urea; DMDM hydantoin; 2-bromo-2-nitropropane-1,3-diol; and diazolidinyl urea. Exposure to paraben preservatives, such as methyl, ethyl, propyl, and butyl paraben, did not cause any allergic reaction in people with eczema in the study.

Choose products with a low water content—for example, ointments, since they usually contain no preservatives—if you have mild eczema and are looking for relief.

Apply a moisturizer within three minutes of a short, warm— not hot—shower or bath using mild, unscented soap. (Pat, don’t rub, skin dry with a soft towel first.)

See a dermatologist if your eczema is chronic, severe, or not relieved by over-the-counter products. He or she can help you sort through skin-care options and prescribe treatment to help relieve inflammation.
