How do foreigners find clinics in Korea? (seeking advice)

Hi everyone, I'm Quynh from Vietnam. I'm planning to try some aesthetic procedures when I go to South Korea, but I really don't know where to start to find a reputable and trustworthy clinic.

My biggest concern is communication – I'm not sure if the doctors there speak good English, or if I'll need to find translation services. And what should I check before booking a consultation?

Do any of you have experience or have heard of someone doing similar things? What do people usually do to ensure a clinic is safe and professional? I feel a bit anxious because this is my first time doing this abroad. Thank you all so much!
