How should I care for myself after a minor procedure in Korea? Could you recommend some anti-swelling products and a packing list?

Hi everyone, I'm Ting. I'm considering getting a minor cosmetic procedure in Seoul, but I'm unsure about post-procedure care. I'm especially worried about swelling; I'm concerned that the flight back home might make my face even more swollen.

I'd like to ask if anyone has had a similar procedure and immediately flown away? What skincare products should I prepare to reduce swelling? I'm wondering if I should buy some products in Korea beforehand, or if it's better to buy them back home?

Also, how long does it usually take before I can return to normal life and work after the procedure? I'm a little nervous, worried it might be too noticeable. If anyone has gone through this, could you share your aftercare experience? For example, cold compresses, what kind of gentle moisturizers are best, and what should I avoid?

Thank you!
