How long does the procedure take if an office worker wants to get fillers during their lunch break?

My forehead has been looking really flat lately, so I'm planning to visit Maypure on a weekday this week. Since I work, I have to utilize my lunch break, so I'm writing this post to ask how long the filler procedure will take. I've read reviews saying it finishes quickly, but then there are also comments saying it takes a bit longer for the molding process... haha. If it only takes about 20 minutes after applying the numbing cream, I think I could just whip it up during lunch. Please, those of you who have actually experienced fillers at Maypure, share the approximate time it takes! Also, I'm curious about the swelling. Can I resume my daily life immediately? I work in the service industry, so I can't afford to be swollen up like an avatar.
