How do you handle language barriers when getting beauty consultations in Seoul?

Hi, this is Yui. I'm thinking about getting a beauty treatment in Seoul this year, but I'm a little worried about the language barrier... Is it okay with just Japanese or English, or will I need Korean as well? What's the reality?

I can speak basic English, but I'm not confident when it comes to detailed medical explanations. I've heard that some clinics have interpreters during consultations, but if anyone has actually gone through that, could you tell me what it was like?

Also, if anyone has any advice on things to prepare beforehand, or apps they use, I'd appreciate any suggestions. I'd love to hear from people in the same situation.
