Will language be a problem when seeking advice at the Seoul race?

Hello, my name is Solongo. I am a K-beauty enthusiast from Mongolia. I am thinking of going to Seoul later this year to get some good consultations at some good hospitals. But one thing is bugging me - is it possible to have a conversation in Mongolian even though I know a little English? Does anyone have any experience?

Are there any hospitals that have Mongolian representatives or staff who understand Mongolian? Or is it normal to simply receive a reception in English? It would be good to know. It really helps.
