Is the language barrier a headache when consulting in Seoul?

Hi everyone, my name is Shan, and I'm recently considering getting some cosmetic consultations in Seoul, but I'm a little worried about the language barrier. My English is okay, but I might not be familiar with medical terms, and Chinese is definitely what I'm most comfortable with. I wanted to ask if clinics in Seoul generally offer Chinese consultations, or if it's only possible to use English or Korean.

I've heard that some clinics offer translation services, but I'm not sure if this is standard or if I need to book it in advance. If I can only use English, I can try, but I'm concerned I might not understand some details clearly. Has anyone here had consultations before? Could you share your experiences? For example, how did you communicate when booking, and what was the consultation like in person?

Also, I'd like to ask, how far in advance do I usually need to book? Do I need to bring identification like an ID card or passport? This is my first time doing something like this, so I'm a bit nervous and hope you can give me some advice!
