Is English enough for consultation in Seoul?

Hello everyone! I'm Indah from Indonesia, and I'm planning a trip to Seoul for an aesthetic consultation. My biggest concern is the language barrier. I'm pretty fluent in English, but not very good at Korean. I'd like to hear from those of you who have had consultations there—are the doctors or staff fluent in English? Or should I prepare a translator as well?

My concern is that important details about the procedure might get lost in the explanation, and I want to be 100% sure I understand what's going to be done. After all, this is an important decision for my body, right?

Can anyone share their experience? Do most clinics in popular areas (like Gangnam or Myeongdong) have English-speaking staff? Or should I specifically look for one that has an Indonesian/English translator? Thank you!
