Is English enough? Or do I need to speak Korean too?

Hello! My name is Best, and I'm from Thailand. I'm planning a trip to Seoul for some beauty treatments and consultations, but I'm a bit worried about the language barrier. I can speak English fluently, but I don't know much Korean. Has anyone here consulted with clinics there before?

I'm wondering if most clinics in Seoul are good with English or if speaking English might lead to misunderstandings about the treatments I want. I'm concerned about having trouble explaining important details. Besides speaking English, are there other ways to help, like using reference photos, or do I need to arrange things in advance?

Has anyone had experience with this when visiting Seoul? Could you share your thoughts? Thank you! 🙏
