Can anyone suggest post-treatment care products I should bring?

Hello everyone! I'm Tam, and I'm about to take a trip to Korea for some minor aesthetic treatments. I'm a bit worried about post-treatment care because I'm not sure what the best things to bring are. I've heard about cooling masks, silicone scar sheets, and soothing gels, but I'm really unsure which ones will be helpful and whether I should buy them in Vietnam or wait to purchase them in Korea.

Secondly, I'm planning to stay in Korea for only about a week, so I want to prepare my skincare items in advance. Has anyone been through this before and can share any experiences? What products made you feel most comfortable during the recovery period? I'm feeling a bit anxious about this, so I'm really looking forward to your advice.

Thank you all so much! 😊
