Language issues when consulting in Seoul — Is English or Chinese sufficient?

Hi everyone! I'm Peichun from Taiwan. I'm recently considering getting some cosmetic treatments in Seoul, but I've suddenly realized something – the language barrier. My English is okay, but not super fluent, and Chinese is no problem, of course. Has anyone consulted with clinics in Seoul? Is it necessary to know Korean, or is English sufficient?

I'm a little worried that if there are complex medical terms or details during the consultation, there might be communication difficulties in English. But I'm also unsure about the general English support in Seoul clinics. Does anyone have experience to share? Should I bring my own translation tools or hire a Chinese translator?

I hope someone can help me out! Thank you!
