As a foreigner, how can I read clinic reviews to avoid making a mistake?

Hi everyone, I'm Wan Chen from Taiwan. I'm currently considering a short treatment in Korea, but my Korean is terrible, and I can't understand the clinic reviews and descriptions at all. Could someone share how a foreigner can determine which reviews are genuine and trustworthy? There seem to be so many five-star reviews on Korean websites, but I don't know how to distinguish them.

My question is, are there any warning signs or suspicious points I should be wary of? For example, do the reviews look very similar, are they exaggerated, or are certain words particularly questionable? I know that review cultures may differ between countries, so I'd like to hear what experienced people have to say.

Also, besides online reviews, are there other ways to determine if a clinic is trustworthy? For example, asking friends, reading about their consultation experiences, or is there anything I haven't considered? Any suggestions are welcome, because I really don't want to waste money or end up with a bad clinic. Thank you!
