Seeking help with language issues in Seoul!

Hi everyone! I'm Qing, and I'm planning a trip to Seoul next year to try out some beauty treatments there. I'm really looking forward to it! But I have one concern: language communication. I mainly speak Chinese, and I can have basic conversations in English, but I'm not fluent.

I'd like to ask if any of you have been to Seoul before: when you were consulting, did you mainly communicate in English? Or do many popular places offer Chinese translation services? I'm a little worried that if it involves some technical terms or concepts, I might not be able to express them clearly in English or there might be misunderstandings.

I'd like to hear your experiences. For example, should I specifically mention that I need a Chinese translator beforehand? Or do you have any suggestions for making communication smoother? I feel more at ease knowing I can communicate well and understand the treatment details better. Thank you!
