As a foreigner, how can I understand Korean reviews? Are there any red flags I should watch out for?

Hello everyone, I'm Yan, from China. I've been considering getting some beauty procedures done in Korea recently, but I've run into a problem – a lot of reviews and information are in Korean, and my Korean language skills are quite limited, so I can't understand them well. Are there any sisters out there who can share how you judge the authenticity of reviews when choosing a clinic? Are there any reliable ways to understand an institution's reputation?

Also, I wanted to ask everyone, when looking at reviews, what are some red flags to definitely avoid? For example, promises of exaggerated results or unusually low prices. How should I protect myself? I don't want to get ripped off, but I'm also unsure what pitfalls foreigners here commonly fall into. Can experienced ladies offer some advice? Thank you!
