How do you tell the difference between genuine and unreliable reviews when it comes to cosmetic treatments in Korea?

Hi, this is Asuka. I'm considering getting treatment at a Korean cosmetic clinic from Japan, but honestly, my Korean isn't that great...😅 Even when I look at online reviews, it's difficult to judge whether the information is truly reliable.

I'm especially concerned about how to distinguish between genuine customer opinions and promotional reviews. Also, I'd like to know about any warning signs to avoid and things to be careful about when contacting clinics... The language barrier is making me even more anxious. 💦

If there are any overseas users who have managed to organize the information effectively, could you please share your tips? I use translation apps, but with medical information, nuances can be lost. How do people actually make these judgments?
