Researchers, including one of Indian-origin, have revealed that face masks worn to stop the spread of Covid-19 can trigger bouts of eczema in people with sensitive skin and allergies. Eczema is a condition that causes inflamed, itchy, cracked, and rough skin. The most common type is atopic dermatitis.

A medically challenging case presented at this year's virtual American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting revealed that for a man with several skin allergies, mask-wearing triggered his contact dermatitis.
