How do you find a truly trustworthy clinic in Korea? (Plus interpreter)

Hi everyone! I'm Fitri from Indonesia, and I'm seriously considering trying aesthetic treatments in Korea. But to be honest, I'm a bit nervous about finding a truly good and trustworthy clinic. Has anyone been there? Especially those who don't speak Korean or whose English is mediocre?

I'd like to know how to check out a clinic before booking, and what questions to ask during the first consultation. Is it better to use your own interpreter or have the clinic provide one? I've never heard from any friends about this, so I'm completely clueless 😅

If anyone can share their experience of the process from start to consultation, I'd be super grateful! Practical tips would also be great. Thanks in advance, everyone!
