I'm Vietnamese and don't know much Korean - how can I trust the reviews here?

Hi ladies! My name is Thao, and I'm going to South Korea soon for some cosmetic procedures, but I'm really confused by the reviews I've read online. My Korean isn't very good, and I don't know how to distinguish between real and fake reviews, or which clinics are just doing marketing. Do you have any ways to check the credibility of a clinic?

I also want to ask if there are any warning signs? For example, what should I look for when viewing before/after photos, or what about promises that seem too good to be true? I don't want to fall into the trap of places that only take money without providing proper care.

I can use Google Translate, but it's not always accurate. Has anyone been to Korea and overcome this problem? Could you share your experience? Or is there a way to contact them directly beforehand, via email or video consultation? Thank you so much! 💕
