What items should I prepare for my post-beauty treatment self-care routine?

Hi! My name is Pat, and this is my first time visiting Korea for cosmetic procedures. I've been planning what post-treatment care products to bring. I'm just not sure which ones will actually help and which ones would be better to buy in Korea. 😅

I'm thinking of bringing cooling sheet masks and silicone scar sheets, along with other products that help with wound healing and soothing the skin. Has anyone had experience with these? Some people have mentioned that certain items are easily available at shops in Korea at reasonable prices. I'm wondering if I should try to find them there or if it's better to bring them from Thailand.

I'd love some advice from those who have been there: what items are truly essential, and what can be safely purchased after the procedure? Thanks in advance! 💚
