How can foreigners find trustworthy beauty clinics in South Korea? How can they verify their credentials?

Hi everyone! I'm Mengju from Taiwan. I'm recently considering getting a minor treatment in Korea, but to be honest, I'm a little nervous. As a foreigner, I'd like to ask how you all find reliable clinics? Are there any tips or things to be aware of?

I'm particularly worried about the language barrier, as I'm concerned about misunderstandings. Do clinics usually provide translators? Or do you need to bring a friend to act as a translator? Or is English sufficient? I want to ensure I can fully understand every detail the doctor says during the consultation and avoid any communication barriers.

Also, does anyone know what else I should check besides reviews when choosing a clinic? For example, their qualifications, their attitude during the first consultation, etc.? I know I can't rely solely on online reviews, so I'd like to hear your practical experiences and advice. Thank you!
