I think so, too. I played in CLINICX, Tsim Sha Tsui some time ago. The doctor told me not to take a sauna, not to soak in hot springs, not to eat irritating things, and not to press my nose (put a little on my nose). I didn't say I couldn't fly.

In fact, hyaluronic acid is a substance that exists in the body itself, so I think it can fly.

If you are worried about the change of air pressure in the plane, don't just sit there. You should rest for a day or two.
