Is English sufficient for a consultation at Seoul? I'm really worried about the language barrier.

Hello! My name is Jiew, and I'm planning a trip to Seoul next month for some beauty treatments. However, I'm really worried about the language barrier. My English is pretty good, but not fluent, so I'm wondering if it will be enough when I consult with the doctors and surgeons in Seoul?

Has anyone been there before? Does the staff speak Thai? Or should I always go with a translator? I'd love to get tips from people who have actually been through this, as it's important for me to clearly communicate my needs.

Are there any apps or other methods I can use? I was thinking of bringing a translation app, but I'd like to hear opinions from other Thais who have traveled there. Thanks in advance!
