Ladies, any tips for post-mild procedure care? What should I pack for travel?

Hi everyone! I'm Chi, and I'm preparing for a minor procedure in Seoul, after which I plan to stay and explore for a few more days. This is my first time, so I'm a little worried about post-procedure care, especially swelling and skincare.

I'd like to ask: after the procedure, is swelling common? How long does it typically last? And what products are essential to bring along? I know I'll need masks and moisturizer, but I'm not sure if anything else is necessary. Can anyone share their experiences?

Thank you all so much! I'm really looking forward to advice from those who have been through this before. 🙏
