I have a question about downtime after getting a nasal injection, before I land back home.

Hi, my name is Bank. I have a question about non-surgical nose fillers. I'm planning a trip to Seoul in a few weeks and would like to try the procedure, but I need to be able to go home within 3-4 days. Has anyone had this done before? How long is the recovery usually? Is there a lot of redness, swelling, or bruising in the first few days?

I'm worried about having to wear a mask home, haha. And after the procedure, how many days can I go sightseeing? I want to know about real experiences, not just what websites say, because everyone's experience can be different.

For those with experience, will the redness disappear in 2-3 days, or do I need to be more patient? Besides that, are there any precautions I should take in the first few days after the procedure? Thank you in advance.
