Regarding nasal injections, how long do I need to rest before flying back?

Hi, my name is Beam. After watching videos and reading stories about non-surgical nose injections, I'm thinking of trying it during my trip to Korea. However, I have questions about how long the swelling and recovery will take, as my flight home is in about 5-6 days, and I don't want my face to be too swollen.

Has anyone had experience with this? What was the recovery like on the first two days after the injection? Was there a lot of swelling? Would using a heat pack or ice help? I'm worried about flying while still swollen. And will air pressure affect my new nasal ridge? Please share your experiences!
