Question regarding the time for the Shurink Universe procedure during an office worker's lunch break.

Now that I'm past my mid-30s, I can feel my facial contours sagging day by day. I used to get compliments on my sharp jawline, but now when I look in the mirror, my cheeks are sagging like a bulldog's, and it's driving me crazy. It's especially stressful when photos cast shadows around my nasolabial folds, making me look older. I've bought lifting products and tried using home care devices, but it seems like it's not enough to lift the skin that has already sagged. I've finally concluded that professional dermatological treatment is the only solution.
I see a lot of people getting ultrasound lifting these days, but there are so many types that it's confusing. Among them, I'm most interested in the Shurink Universe because it is said to be less painful and provide fast results. I heard it hurts less and the procedure is more thorough than the previous versions, so I think it would be perfect for someone like me who gets easily scared! However, since I work, I feel a bit self-conscious about taking time off to get the treatment. I'm thinking of squeezing in some time during my weekday lunch break to visit Maypure near my office, but I can't bring myself to make an appointment because I'm not sure how long it will take.
How long would it take, roughly from the time I wait with the numbing cream applied until I see the doctor and the procedure is finished? If any office workers have received the Shurink Universe treatment, please let me know if it's possible to get it done within an hour of lunch break haha. I'm also curious if the redness or swelling tends to be severe immediately after the procedure. I have to return to the office this afternoon for meetings and socializing, so it would be awkward if it were too noticeable ㅠㅠ. Please give me some realistic advice on whether it can be covered up immediately with makeup or if wearing a mask is mandatory! If it's too tight to get it done during lunch or if it's too noticeable, I'm debating if it would be better to just book an appointment for the weekend to get the Shurink Universe treatment with peace of mind. I look forward to your valuable comments from those with experience. Thank you haha.
