Is this English sufficient for someone seeking advice in Seoul?

Hi! My name is Fern. I have a question for those who have had aesthetic treatments at the old Selena Clinic. I'd like to know if the doctors at the various clinics are proficient in English, and if it will be convenient during consultations. I'm a bit worried about the language barrier. I speak English well enough for a tour, but I might be confused about technical medical information.

Some friends say they met doctors who spoke excellent English, while others said they needed a translator or came with a friend who speaks Korean or Thai. I'm wondering if it's really that different at each clinic, or if most are okay with English. I'd love to hear from someone who has actually been there so I can plan well before I go.

Could anyone who has been there share how they managed the language barrier and what additional preparations they needed? Thank you in advance!
