Language at Seoul Consult — Just English or Do You Need Korean?

Hello everyone! I'm Rina from Indonesia, and I'm planning to have an aesthetic treatment consultation in Seoul next month. My main concern is the language barrier — I can speak English reasonably well, but I don't know any Korean at all. Has anyone had a consultation experience using only English? Do the doctors and staff understand well enough, or would it be better for me to bring a translator?

For those who have been there, do clinics in Seoul accommodate foreign patients with English? I'm worried about getting detailed explanations of treatments and accurate Q&A, especially for medical aspects. Does anyone have any communication tips that worked for them?

This is my first time consulting abroad, so I'm a bit nervous haha. Thanks in advance to anyone who shares their experience!
