Wearing personal protective equipment has become more important than any time in the past due to the COVID-19 pandemic. A combination of a face mask and goggles commonly results in fogging of the goggles. This obscures the view and might potentially affect the quality of patient care. The use of paper tape is a simple and effective anti-fog method.[12] However, paper tape might cause some local skin irritation in some individuals.


Hydrocolloid dressing can be used as a potentially less irritating alternative. Hydrocolloid dressings are used to provide a moist environment and promote wound healing in a wide range of conditions in dermatology. A piece of hydrocolloid dressing (DuoDERM Extra Thin, ConvaTec, Oklahoma, USA) is cut into long strips [Figure 1]. A strip is applied to the upper border of the face mask to prevent fogging [Figure 2a and b]. It is easily applied without the need for any assistance. The hydrocolloid sheet is commonly available in dermatology clinics and costs approximately 2-3 US dollars per sheet. Allergic contact dermatitis due to hydrocolloid dressing can occur but appears to be infrequent.[3]
