What do you bring back for aftercare following beauty treatments in Korea?

Hi everyone! My name is Tuyen, and I'm going to Korea soon for some treatments and want to prepare thoroughly for the recovery phase. I'm struggling to decide what to bring from Vietnam because I'm worried about finding things there being expensive and unfamiliar. Do you have any experience with this?

I'm thinking of bringing cooling masks, silicone patches to cover scars, and soothing gel from home. But I'm not sure if it's necessary, or if these things are available at pharmacies in Korea. What do you usually bring? Do I need to prepare too much, or just the basics?

I'd really appreciate it if you could share your experiences with me! 🙏 Thank you!
