How do foreigners view Korean reviews? Are there any red flags that should be noted?

Hi everyone! I'm Mengju from Taiwan. I've recently been researching cosmetic procedures in Korea, but honestly, my Korean isn't very good, and I'm struggling to read clinic reviews. I see some five-star reviews and some very negative ones, and I can't tell which are genuine and which might be fake or manipulated by the clinics themselves.

Could anyone share how a foreigner can judge the authenticity of reviews? For example, what aspects seem particularly suspicious? Like reviews that are overly perfect or praising a specific doctor—are these red flags? I'm also unsure how to use translation software and whether I'll miss important information.

Also, if I'm fluent in English or Chinese, how can I confirm with the clinic beforehand whether they accept consultations in English or Chinese? Has anyone tried this? I really want to find reliable places, but I'm afraid of making a bad choice. Thank you for your suggestions!
