According with this study, N95 respirator masks are made of polypropylene fabric processed by a non-woven technology and should fit tightly to the face to be effective.
The study by Foo and colleagues revealed that 35.5% of the staff who used N95 masks regularly experienced acne, facial dermatitis and pigmentation of nasal bridge, cheeks and chin. In this study, acne was one of the most prevalent skin reactions related to the use of N95 respirator masks.
The dermatitis that often presented with pruritic skin lesions was mostly irritant type but allergic contact dermatitis due to ADHESIVES or other parts of the respirator masks such as RUBBER STRAPS and METAL CLIPS was also reported.
Several factors including humidity, warm environment and occlusion due to local pressures could explain the exacerbation of these conditions.
Protecting healthcare workers (HCWs) is crucial during Corona Virus Disease 2019 pandemic and requires wearing personal protective equipment (PPE) . While most of the studies have focused on the skin reactions caused by gloves, other PPE such as gowns, respirator masks, face shields and goggles are also worn by HCWs for long hours during the current epidemic and skin irritations caused by these equipment may cause discouragement of health workers from using them . In this letter we have focused on the reaction caused by non-glove PPE.
