When looking for a clinic in Korea, how do people find trustworthy ones?

Hi, this is Misaki. I've recently become interested in cosmetic treatments in Korea, but honestly, I don't know how to find a trustworthy clinic... Especially since I'm a foreigner, I'm worried about whether I'll be able to communicate properly.

What points do you all consider when choosing a clinic? For example, do you check if they offer Japanese-language support during the initial consultation, or if they have interpreters? I'd like to know about these practical things. Also, what should I check during my first consultation?

There's so much information on social media and review sites, it's hard to judge what's reliable. I'd love to hear experiences from people who have actually received treatment in Korea, or stories like, "They explained everything properly here." Please also share any tips you have regarding language barriers or clinic selection!
