What did you bring back from your trip after the treatment?

Hello, my name is Nomin. I'm traveling to Korea at the end of this month to get some beauty procedures done. I'm thinking of bringing some items to use after the treatments. I was wondering if anyone could give me some advice.

Should I bring things like cooling masks, silicone scar sheets, or soothing gels? What brands do people recommend? I'm really unsure – I don't know exactly which masks to use after which treatments for this type of procedure. I'm also concerned it might be difficult to bring these things from Mongolia.

If you've made a similar trip before, could you share some thoughts? What items were genuinely helpful? Do you know the prices, how much these items cost in Seoul? Thank you!
