What products should I bring for post-procedure swelling reduction and at-home care after a minor treatment in Korea?

Hi everyone! I'm Jia-Hui from Taiwan. I'm planning a small treatment in Seoul next month (haven't decided on the specific procedure yet) and wanted to ask for advice on post-treatment swelling and care.

I'm a bit worried about how noticeable the swelling will be on my flight back to Taiwan and during the flight itself. I'm also unsure about what products to bring home for aftercare. Has anyone had a similar treatment? How long does swelling typically last? Should I prepare ice packs, soothing masks, or other items? Are general over-the-counter swelling relief products effective, or do I need specialized medical-grade skincare?

Also, I'm wondering if they'll recommend specific aftercare products at the clinic in Korea. I'd love to hear about your experiences – is it okay to bring my usual skincare products, or is it better to use Korean products for peace of mind? I haven't set a budget yet, so I'm hoping to get some advice from experienced members first. Thanks!
