If a cloth mask is causing skin irritation, ladies can avoid wearing makeup. I haven't worn foundation since lockdown. 😳 I don't want to think about how my makeup would feel under a mask, even after 30 minutes. Ugh. Highly perfumed aftershaves could be a problem for men.
We wash all our masks (and general laundry) in Free&Clear type detergents and never use fabric softeners or dryer sheets due to allergies. Their oily residue and/or their perfumes can cause skin breakouts for sensitive skin.
I suggest to friends who will wear the cloth masks I've made for them for work that they change them out after 2-3 hours and put on a fresh one. I give them three or four, and encourage them to wash them every night. They can be hand washed in the sink. This virus is susceptible to soap/detergents so hot water isn't necessary. We don't boil wash our hands during the day, and that works.
We prefer the pleated style to the contour style that is more prevalent on the internet and we see almost everywhere. Those contour ones are not 'one size fits all' and the majority of improperly worn masks are that style.
Cotton breathes better than synthetic fabrics, IMO.. The masks I make include a sleeve on the inside for a nose wire. This helps it fit better at the top of the nose and really cuts down with the glasses lens fogging.
