What do you bring for post-aesthetic care in Korea?

Hello everyone! I'm Giang from Vietnam, and I'm coming to Korea soon for some minor cosmetic procedures. I'm preparing for my recovery at home and don't know what to pack. I've heard about cooling masks, moisturizing creams, and silicone sheets to help with skin recovery, but I'm not sure which products are truly helpful.

Does anyone have experience shopping for pre-procedure care items? What do you pack in your luggage? I'm unsure what to prioritize first – cooling masks or moisturizing products? And is it better to buy them in Vietnam beforehand or look for them in Korea?

I'd also like to know what products people usually use for post-procedure care. Thank you all so much!
