Language barrier at consultations in Seoul — is English enough?

Hey everyone! I'm planning a trip to Seoul soon and I'm thinking about getting a consultation for a treatment I've been wanting to try. My Korean is basically non-existent (lol), so I'm wondering how realistic it is to do a consultation in English? Has anyone here done this? I'm curious if most places in the popular areas have English-speaking staff, or if I should try to find someone who speaks my language specifically. I don't want to end up confused about what they're recommending, you know? Also, is it worth bringing a translator or using translation apps during the appointment? Would love to hear about your experiences!
