How often do you need to evacuate after injecting fillers into your nose?

Hello, friends! I'm Bolor, from Mongolia. I'm coming to Korea this month and I'm thinking of taking a few days of training on my nose. But I have to fly, so I need to go back and forth for friendship and work. Does anyone know anyone who has had filler injections? How often do they need to be repeated?

In short, is it possible to come back within a week, or should it be longer? I made an appointment to come back in two weeks. I'd like to hear your experiences! Does anyone know anyone who has had the same thing done before?
