What do you pack for your post-beauty trip skincare routine from South Korea?

Hello everyone! I'm Ngoc, and this will be my first time flying to Korea for some aesthetic enhancements. I'm packing my bags and feeling a bit anxious about post-treatment care. I'd love to know what those who have traveled before usually pack in their suitcases. I'm wondering if I should bring cooling masks, scar reduction patches, or soothing gels from Vietnam, or if it would be better to buy them there?

I've heard that meticulous care is needed in the first few weeks after treatment, but I'm not sure what specific items to bring. I'm worried that if I don't prepare well, the recovery period will be difficult. Can you share your experiences? What products did you find truly helpful during your recovery? Thank you all so much!
