What do you ladies pack for recovery after beauty treatments in Korea?

Those of you who have been to Korea for beauty treatments know how important the recovery phase is. I just finished a treatment and at first I was worried and didn't know what to pack to bring back. I was thinking about buying some supportive products like cooling masks, silicone scar sheets, or soothing gels there, because it seems like the prices in Korea would be cheaper.

Now I'm curious what other women usually pack to bring back? Which ones are really useful in the first few days of recovery? I'm not sure if I should buy these things there before returning, or if I can find them in Vietnam. I heard silicone sheets can help, but I've never used them, so I'm a little worried 😅

Anyone with experience, please share your tips! I want to prepare thoroughly so that the recovery process goes as smoothly as possible.
