Just asking, which area is the best for a beauty trip in Seoul?

Hey, I'm Maya from Indonesia! So I'm planning to go to Seoul next month specifically for skin treatments and aesthetics. It's my first time, so I'm still unsure where to stay most conveniently.

I've heard Gangnam and Apgujeong are really popular for beauty treatments, but I don't know the difference between them and other areas. Where would be more worthwhile? And what about hotel locations—is it better to be close to the clinic, or is it better to find a chilled area but close to public transportation?

Has anyone been to Seoul for a treatment? What was your experience like? How long do you usually stay to enjoy the area and have enough recovery time? I want to explore more, not just rely on the clinic, hehe.

Any tips from experienced travelers? Thanks in advance! 🙏
