Where do you usually go for beauty treatments in Seoul? Gangnam or Apgujeong?

Hello everyone! I'm Loan, and I'm planning my first trip to Seoul for some skin treatments. I've heard a lot about Gangnam and Apgujeong online, but I'm not sure which area is actually better for this beauty trip.

Has anyone here been to these areas? I'd like to know which area has more clinics, or if both areas have good facilities. What about accommodation – should I stay near these areas, or is it okay to stay elsewhere and commute?

I'm also new to Seoul, so besides treatments, I'd like some time to explore a bit. I'd appreciate it if you could share your experiences, especially those of you who have traveled from abroad for beauty treatments in Seoul. Thank you so much! 😊
