Is English sufficient for consultation in Seoul, or do I need to speak Korean?

Hi, my name is Pim from Thailand. I'm planning to have some beauty treatments in Seoul, but I'm worried about the language barrier. I speak English fluently, but not Korean. My question is, will the English proficiency be sufficient during the clinic consultation? Has anyone from Thailand gone to Seoul for this experience? I'd really appreciate hearing about it.

I have many concerns, especially regarding the results I want to achieve. There are things I need to explain in detail, and I'm worried that if the staff doesn't understand what I want, there will be problems. Will the clinic have staff who speak English? I'm not sure what that's generally like.

Or what should I prepare for this consultation? Any advice would be greatly appreciated. Thank you in advance!
