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

I'm Thao, and I'm planning to try some beauty services in Korea, but I only speak English and Vietnamese. When I look at review sites, they're all in Korean. Some can be translated with Google Translate, but it doesn't feel very accurate. Can anyone with experience help me? How can I distinguish real reviews from fake ones?

Another thing is, I want to know what "red flags" I should watch out for. For example, what in a review or their approach might be a trap? I want to be sure before booking an appointment. If anyone has gone through this experience, could you please share some tips? 🙏
