Is it okay to consult in Seoul using only English? I'm worried about the language barrier.

Hi, it's Akari. I'm thinking of going to Seoul for a cosmetic consultation next month, but I'm a bit worried about the language barrier. I can speak English reasonably well, but there are times when I want to explain subtle nuances in Japanese...

For those who have actually gone for consultations, were you okay with just English? Or would it be better to hire an interpreter? Also, does it vary by clinic? Are there places with staff who speak Japanese, or should I confirm this when I first contact them?

I think it's important to convey detailed requests and concerns, so I don't want to mess up the communication. What do you all do? I'd really appreciate any experiences or advice you can share.
