Consultation in Seoul without Korean—just English or do I need an interpreter?

Hello everyone! My name is Salsa, and I'm planning to have a consultation for aesthetic treatments in Seoul next month. My main concern is the language barrier—I can speak English but not Korean at all. Has anyone had experience consulting there before? Are the doctors and staff usually fluent enough in English?

I'm worried that important details might be missed due to miscommunication, especially when discussing expectations or technical questions about the treatments. Or do I need to arrange an interpreter myself beforehand? The additional expense for that is also a consideration.

If anyone has experiences or tips on how to navigate a situation like this, I would super appreciate it! Thanks in advance 😊
