How can a foreigner like me read reviews to make them trustworthy? 😅

Hi, my name is Tum and I'm from Thailand. I'm thinking of going to Korea for my first beauty treatment, but the problem is I can't read Korean well at all 😭 When I search for clinics, there are tons of reviews, but I don't know which Google or other websites are trustworthy.

I'd like to ask other foreigners how they check and choose what to trust in reviews. What are some warning signs that a clinic might be bad or fraudulent? For example, if the language or their demeanor are suspicious, or they speak rudely or inappropriately, how can I know to be cautious?

Can anyone recommend what questions to ask when contacting them, or what pages/apps are commonly used by foreigners? Thank you in advance 🙏
