Foreigners want to get beauty treatments in Korea, but they don't understand the reviews. 😅

Hi, my name is Pim, and I'm from Thailand. I'm currently studying about beauty treatments in Korea, but my problem is that I don't read Korean very well. I mostly rely on online reviews, but I'm afraid of being misled or encountering bad clinics.

Could anyone tell me what to look for in reviews, how to read them to make them trustworthy, and what red flags to watch out for? For example, Korean language might look different from market reviews, or if a review is from a friend of a friend, should I trust it? 😅 Personally, I'd like to know how foreigners can help me, from asking doctors to checking the clinic's credibility. Any advice from those with experience would be greatly appreciated.
