As a foreigner, how can I find a reliable clinic in Korea?

Hello everyone, I'm Qing. I've been thinking about getting some aesthetic procedures done in Korea recently, but as a Chinese national, I'm feeling a bit lost about how to find a clinic. There's so much information online, with some people emphasizing reputation and others recommending this or that, but I'm still not entirely at ease.

I'd like to ask everyone, how do you choose a clinic? What's most important? For example, is it essential to confirm that the clinic offers translation services, or that consultations can be conducted in English or Chinese? I've heard that some clinics have experience with international patients, but I don't know how to determine if a clinic is truly reliable.

Also, what questions should I ask during the initial consultation? Are there any red flags I should be aware of? I don't want to focus solely on price, but I also want to be fully informed before making a decision. If anyone has gone through this process before, could you share your experiences? Especially regarding language communication and peace of mind. Thank you!
