Is it possible to get fillers during my lunch break? I have a question about the procedure time!

Now that I've lost all my baby fat, my face looks so tired. I'm frantically busy with continuous overtime, but I feel like I need to get some skincare and a cosmetic procedure before I age any further. I'm thinking of getting a little filler for my nasolabial folds, but time is the biggest issue. I feel a bit hesitant to take a half-day off work, so I want to squeeze in a quick filler injection during my lunch break or right after work. How long would it take in total, including the application of numbing cream and the consultation? To all the busy Korean office workers out there who have managed to squeeze in fillers while working, I would be very grateful if you could let me know the approximate procedure time, excluding waiting time.
