Has anyone brought any good recovery products?

Hello! I'm planning a trip to Seoul soon for medical aesthetic treatments and I'm wondering what I should bring to ensure a smooth recovery. I'm particularly interested in things like cooling masks, silicone scar sheets, and cica gel – do these items actually help after a procedure?

I know some of these can be a bit pricey, but I'm unsure whether it's easier to bring them from Mongolia or purchase them there. I'd love to hear about your experiences – what products were genuinely helpful after your treatments? Has anyone brought back any post-procedure care items from their medical tourism trips? I'd appreciate your recommendations!
