Is English sufficient for consultations in Seoul?

Hello everyone! I'm Intan, from Indonesia. I'm planning an aesthetic consultation in Seoul next month, but I'm a bit worried about the language barrier. My English is just so-so, haha. My question is, can most clinics in Seoul handle consultations in English? Or should I prepare a translator, or what do you recommend?

I've looked at a few clinics that claim to have staff who speak Indonesian or English, but I'm not sure how common that is. Also, can they usually explain treatment options in detail using English, or is it a bit complicated?

I'd be thrilled if anyone with experience could share! What's usually smoother — booking directly, using a translator app, or what's the best practice? Thanks in advance! 😊
