Items to Prepare for Post-Treatment During a Korea Trip

Hi, I'm Ning. I'm planning to go to Korea for cosmetic treatment at the end of this month, but I'm still not sure what I need to prepare for post-treatment skincare. I'm thinking about whether I should pack cooling masks, scar reduction stickers, or gels that will help with recovery.

Has anyone here been for treatment like this once or twice before? Could you share what things you were worried about and what you really needed? People say you can find these products there, but I think it's better to prepare them from Thailand for peace of mind. There are so many online shops with lots of options, but I'm not sure which ones are really suitable for someone who just had treatment.

Thank you in advance for your recommendations 😊
