How do you handle language barriers when consulting in Seoul?

Hi, this is Hana. I'm planning to get a beauty consultation in Seoul next month, but I'm a little worried about the language barrier...😅

I can manage simple everyday conversations in English, but I'm honestly not confident about medical explanations or subtle nuances. I've heard there are clinics where Japanese is spoken, but what's the reality? Are there people who manage with just English? Or should I bring a translation app...?

Since it's my first consultation, I'm worried about whether I'll be able to properly convey my wishes and concerns. If anyone has been in a similar situation, I'd love to hear what strategies you used!
