Is English sufficient for a clinic in Seoul that doesn't speak Thai?

Hello, my name is Pin and I have a question about language. I'm planning a trip to Seoul for beauty treatments but I'm worried about communication because I don't speak any Korean.

Has anyone been there? Is English sufficient for confirming appointments, consultations, and discussing treatment details? Or is it necessary to hire a translator? For general clinics in popular areas, I assume there might be some staff who speak English, but I'm not entirely sure.

Honestly, I'm quite excited but also a little worried. Does anyone have any experiences or tips to make the identity verification and consultation process go smoothly? Thank you in advance.
