I never wore a mask, but my children are afraid of altercations, they put it when go to stores and restaurants etc. My yangest daughter whent to Arizona, it was hot there and she was wearing a mask, when she got back home after couple of days she got red eaching spots on her face. Later we find out that it could be from wearing mask and when it’s hot the bacteria is collecting under the mask and if you scratch or pump a pimple you could get bacteria spreading. That is how she got impetigo, never heard about it before.
