What did you bring for aftercare following your beauty trip?

Hi, this is Aya. I'm going to Korea next week for a beauty trip, but honestly, I'm a little worried about aftercare...😅 I know there will inevitably be redness and swelling after treatments, so I want to prepare in advance.

What do you all bring with you on trips like this? Cooling masks, silicone sheets, soothing gels, etc.? I'm not sure if things I can buy at a drugstore are okay, or if there are specific products you recommend...😅 I also want to bring only the absolute essentials because I'll have a lot of luggage to carry.

If anyone has experience with this, I'd love to hear what items you found useful. Also, any information about your aftercare routine would be helpful. Thank you!
