By request, this mod adds the ability to purchase Spa Day face masks from mirrors like you can from computers and the mini fridge.
You have to apply the masks in a separate step from a sim’s inventory because it wouldn’t cooperate to actually apply them. I’m just happy I got it to stop throwing errors so I’ll take what I can get for now.

Requires Spa Day & the XML Injector
The great thing about using the XML Injector is that I didn't have to override all the mirrors to make this work! Anything with the mirror tag that my snippet is looking for will get the interaction.
