Post-beauty procedure care in Korea... what does everyone bring?

Hi, it's Mio! I'm planning a trip to Korea next month for some minor cosmetic procedures, and I'm a bit worried about aftercare. I heard that the recovery period after treatments is short, so the care items you bring are really important... What did everyone else prepare?

I'm particularly interested in things like cooling masks, silicone sheets, and soothing gels. I feel like it would be safer to bring them from Japan, but what do you all think? If I can get them at Korean drugstores, I could pack lighter...

If anyone has experience, I'd love to hear stories like, "I was so glad I brought this!" or "This was perfectly fine to get there." Also, how did you care for your skin during the first few days after the procedure? I'm feeling a bit anxious, so any advice would be greatly appreciated!
