How do foreigners typically choose a reliable clinic in Korea?

Hello everyone, I'm Rong. I've been thinking about getting some skin management done in Korea recently, but as a foreigner, I'm a bit worried. I wanted to ask everyone, how do you find clinics you can trust? I'm particularly concerned about language issues with translation and consultations – has anyone been able to share their experiences?

I've heard that some clinics provide translators or offer consultations in English, but I'm not sure how to confirm this in advance. Should I just call them directly? Or are there other reliable ways? Also, is there any homework I need to do before going? For example, what should I look out for when reading reviews?

I know that cosmetic treatments in Korea are very advanced, but as a foreigner, I still feel a bit uneasy. If anyone has gone through this process before, I would be extremely grateful for any advice. I'm especially keen to hear how everyone ensures smooth communication and how they determine if a clinic is reliable.
