How do foreigners view Korean reviews? Are there any red flags to watch out for?

Hi everyone, I'm Peijun from Taiwan. I'm thinking about getting some aesthetic medical treatments in Korea recently, but my Korean is really limited, and I can't understand Korean review sites at all... Has anyone else been in the same situation?

I'm really afraid of being scammed or having a bad experience, so I wanted to ask you all – how do you judge if a place's reviews are genuine? Are there any red flags that you can spot even if you don't understand Korean? For example, right now I can only rely on translation software or ask friends, but that's quite time-consuming.

Also, do you trust places with a lot of five-star reviews? Sometimes they feel a bit too good to be true, don't they? Or conversely, do a lot of negative reviews not necessarily mean it's bad? I know this is subjective, but I'd really love to hear about your experiences. Can anyone share how they do their research?
