Tips for managing swelling and aftercare products to bring when traveling after a minor procedure?

Hi everyone! I'm Wulan from Indonesia, and I'm planning to have a minor procedure done in Korea in the next few weeks. But I'm a bit worried about swelling and how to manage it, especially since I'll be traveling extensively right after.

So my question is, for those who have gone through a similar procedure, what aftercare products are worth bringing for travel? I've heard sheet masks and cooling gels are important, but what else is recommended? Also, how long does the swelling usually take to go down? I'm afraid my face will still be swollen when I return to Jakarta.

Additionally, are there any other tips to minimize swelling? Like sleeping position, foods to avoid, or skincare routine changes? I'm a complete newbie to this, so I'd really appreciate any input from those who have experience. Thanks in advance! 🙏
