How do foreigners find good clinics in Korea?

Hello friends! I'm Solongo from Mongolia. I'm thinking about getting cosmetic treatments in Korea this year, and I'm asking for advice on how to find a good clinic. Even if you've decided on a specific treatment, finding a good establishment can be difficult.

For foreigners, what factors do you carefully check when choosing a clinic? For example, whether there's an interpreter during the consultation, or if communication in English is possible. It's true that it's hard to verify information after reading reviews from various websites.

If you've found a clinic this way before, I'd like to hear about your circumstances and how much time you spent. I'm especially interested in your feedback regarding language barriers and unverified information. Thank you!
