Looking for the best areas in Seoul for a beauty trip + hotel recommendations!

Hello everyone! I'm Adelia from Indonesia, and I'm planning a beauty trip to Seoul next year. I really want to explore areas famous for aesthetic treatments and skincare, especially Gangnam and Apgujeong, which I've heard a lot about from friends.

What I'm curious about is, which area do you think is better for foreigners? Is it true that Gangnam is busier and has more clinic options, or is Apgujeong more exclusive and worth it? I also like shopping, so I'm looking for an area with good malls and cafes.

Oh, and about accommodation... does anyone have recommendations for hotels or guesthouses near these beauty areas? I prefer places that are walkable and have easy subway access. Budget-wise, I'm still waiting to find out once I do more detailed research, but the idea is not to spend too much.

Has anyone been there before and can share their experience? I'd love to hear your stories! 💕
