/cgl/ - Cosplay & EGL

Not sure exactly if this is the right thread to ask this in or not, but whatever.

Anyone have experience with using a medical face mask with makeup on? I don't normally crossplay with a face mask on, but as I'll be recovering from a cold, I'd rather not risk getting others sick.
My first assumption would be that makeup would get all over the under-side of the face mask and things would get bad fast.
