Has anyone shared how to find a reliable clinic in Korea?

Hi everyone, I'm Hui from China. I've been thinking about getting some medical aesthetic procedures done in Korea recently, but honestly, I'm a bit anxious. I've heard many people go to Korea for treatments, but I have no idea how to find a trustworthy clinic. There's so much information online, some of it looks like ads, and I can't tell if some of it is real or fake.

I'd like to ask for your advice: how do you usually find clinics in Korea? What channels do you use to get information? And what about the language barrier? My English is okay, but I don't know a single word of Korean. How does everyone communicate? Do clinics provide translators directly, or do you have to figure it out yourself?

Also, I'd like to ask what questions you usually ask the doctor during consultations? Are there any red flags I should pay special attention to? I want to do my homework before I go, so I'd appreciate it if experienced sisters could share their insights!
