How to Read Korean Reviews When Getting Cosmetic Procedures in South Korea?

Hi everyone, I'm Kim from Vietnam. I'm planning to get some treatments in Seoul for the first time, but I'm really unsure how to read and trust reviews. My Korean is very basic, I can only guess a little with Google Translate, but I'm worried machine translation won't be accurate or will miss important details.

Has anyone been in a similar situation? What's the best way to find reliable information? Should I look for reviews in English instead of relying on Naver or Google Maps? And can you point out any red flags when reading reviews – for example, things that make you think, "hmmm, I shouldn't like this"?

I'd also like to know: when contacting places, are there any important questions I should always ask to ensure we're communicating well despite the language barrier? Thanks in advance! 💕
