How do foreigners find reputable clinics in Korea?

Hello everyone! I'm Lien, from Vietnam. I'm planning to research aesthetic services in South Korea but feel quite lost because I don't know how to verify the credibility of clinics. Can anyone with experience share their insights?

I'm particularly concerned about language barriers and interpretation. During initial consultations, did you request an interpreter, or did the doctors speak English/Vietnamese? I want to ensure I fully understand the medical information, especially risks or contraindications, and I'm afraid of missing crucial details due to misunderstandings.

Secondly, when choosing a clinic, what do you usually check? Are there ways to verify a doctor's credentials or see testimonials from international patients? I know many clinics have English or Vietnamese websites, but I'm unsure if that's a sign of credibility. I'm really looking forward to hearing your experiences!
