Is it okay to wear makeup when going for Ultherapy?

I was only thinking about the procedure itself.
Now that I'm actually trying to make a reservation, I'm becoming curious about these little details.

Whether I need to wash my face before the procedure
I'm not sure if it's okay to at least apply basic makeup.

I plan to go to the hospital right after work.
I think I will be visiting with makeup on.

For those who have received Ulthera...
Do you remember if there was anything you needed to prepare separately before the procedure?
