Finding a clinic in South Korea is difficult... How do foreigners find trustworthy places?

Hi, this is Yumi. I'm thinking about getting cosmetic procedures in Korea, but I'm having trouble choosing a clinic. Information is limited from Japan, and there's the language barrier... How do you all find trustworthy clinics?

I think a pre-treatment consultation is crucial, but I'm worried about whether they'll provide an interpreter and whether I'll be able to properly communicate my needs. I'd like to find a place that offers services in English or Japanese, but where's the most reliable place to gather that kind of information? There are so many options: social media, review sites, etc...

Also, are there any things I should confirm when I actually have a consultation? Like, any red flags? If you're a foreigner who's had procedures done in Korea, please share your experience!
