How to trust reviews when you don't know much Korean?

Hi everyone, I'm Ngoc from Vietnam. I'm planning to try some treatments in Korea, but I'm a bit nervous because I can't read Korean very well. I've seen many reviews on different platforms, but I'm unsure how to tell if they're trustworthy.

Does anyone have experience reading reviews for clinics there? I'd like to know where I should look for information to be sure. And what are some red flags I should watch out for? For example, is a review that's too good to be true a problem? Or what about clinics that are too new or too old?

I'm also wondering if I should rely more on reviews from foreigners or from Koreans. Do you have any suggestions? I'm worried about ending up at a bad place because I'm a foreigner. Thanks to anyone who can help me!
