I was working on three television series during the pandemic lockdowns, and currently working on one right now.
At first it was wearing a lot of PPE, (face shields / goggles, masks, gloves, gowns), social distancing, and the usual hygienic and area sanitation protocols which we had in place before COVID.
Now two years in, and armed with a better understanding of how SARS / COVID works, the use of PPE is down to just wearing masks, our usual hygienic and sanitation protocols have remained in place. We now use air filtration systems (Air Movers for short) in all spaces, so now social distancing is self-monitored and not "heavily" enforced. Despite a 95%+ double vaccination rate, everyone still has to do the usual mandatory COVID testing three times a week.
Having said all that, my make-up application routines are pretty much the same as before COVID. Just everyone is more aware of make-up sanitation procedures and protocols now.
