How to trust reviews when you don't know Korean? 😅

Hello everyone, I'm Bich from Vietnam. I'm planning to get some treatments in South Korea but I'm really struggling because I can't read Korean. When I look at local review sites, I can only use translate and I don't feel very confident. Has anyone else been in this situation?

I'd like to ask what you usually rely on to trust reviews. Are there any red flags I should be careful about? For example, is a review that's too good to be true unusual, or is there a way to tell if a review is genuine?

Also, has anyone used any apps or methods to find more reliable information as a foreigner? I really want to prepare thoroughly before booking appointments. Thank you everyone! 🙏
