Has anyone ever brought their own aftercare products to Korea? Please share some recommendations!

Hey everyone, so I'm planning a trip to Korea next month for some minor treatments and I'm a bit nervous about the recovery process. I've done a lot of googling, but I want to ask directly from those of you who've been through it—should I bring my own stuff from here or buy there?

I was thinking of bringing cooling masks (the freezable kind), silicone scar sheets, and soothing gels or serums from home. But I also know that Korea probably has better options and more affordable ones? I'm also worried about the hassle of packing a lot of items.

How do you guys usually do it? Is there anyone who prefers buying aftercare products there, or do you feel more comfortable bringing your own because you're already familiar with them? I really want to make sure my skin recovers well while I'm there and after I get back too. Thanks so much in advance for your insights! 🙏
