How do you guys find a trustworthy clinic as a foreigner? Any tips?

Hey everyone! I'm planning a trip to Korea in a few months and I'm thinking about getting some aesthetic treatments done while I'm there. But honestly, I'm a bit nervous about finding a good clinic—like, how do you even know who to trust when you don't speak Korean fluently and you're not familiar with the clinics there?

I've been doing some research online, but there's SO much information and I'm not sure what's actually reliable. Does anyone have advice on what to look for? Like, should I be checking if they have English-speaking staff or an interpreter available? I'm worried about miscommunication during the consultation, especially since aesthetic stuff requires being super specific about what you want.

Also, how did you all approach getting consultations? Did you book beforehand or just walk in? And what kind of questions did you ask to feel confident about a place? Any red flags I should watch out for? I'd love to hear from people who've actually done this before!
