During the early months of this pandemic, salons, theaters, dining establishments, and physical stores that sell non-essential goods were closed. Make-up and beauty products were being sold at really low prices online. I bet a lot didn't see any reason to wear make up/put on perfume considering only essential travel was allowed. Plus the uncertain economic climate made people want to curb spending.
Even when restrictions began slowly easing, masks were still in place. The only times that felt reasonable to wear lip products (aside from a lip balm) were during gmeets/zoom/vid calls when we are required to turn on the screens.
So it's only now that I'm almost through with these products.
