What do you buy to bring back after getting a beauty treatment in Korea?

Hi everyone! My name is Trang, and I'm going to South Korea soon for some minor cosmetic procedures and want to prepare thoroughly for the recovery phase. I'm struggling to figure out what to buy, especially post-treatment care products.

I've seen people mention things like cooling masks, silicone patches, soothing gels... but I'm not sure which ones are really helpful in the initial post-treatment period. Can you share what you brought? Are there any items you found really helpful or unnecessary?

I'm also unsure how much to pack, as the clinic might provide some things. Any advice would be appreciated! Thank you so much! 🥰
