Regarding nose injections in Korea, how long is the recovery time?

Hi, my name is Ploy. I'm going to Korea for the upcoming festival in a few days and I'm thinking of trying a non-surgical nose filler injection. However, I have concerns about the recovery time because I'll be returning to Thailand in about 4-5 days after the procedure.

I'm wondering how long the downtime usually is. Has anyone tried this and what kind of recovery period or swelling/redness did you experience? Will the swelling and redness be noticeable? Does ice or anything else help speed up the recovery? I'm not sure if it's really that important.

I'm not sure if I should discuss this with the person performing the procedure beforehand, but I'd really like to hear from someone who has actually gone through this. Thank you!
