Q&A from our international friends! Recommendations for areas and accommodations for a beauty trip to Seoul

Hi everyone! My name is Aom and I'm planning to visit Seoul for the first time for beauty treatments. I'm really confused about choosing the right area. I've heard that Gangnam and Apgujeong are beauty hotspots, but I'd love to hear from you foreigners who've been there already — which area is actually best for someone like me who wants professional consultation on skincare routines? And which neighborhood should I stay near?

Right now I'm looking for accommodation that's not too expensive but in a convenient location, with easy access to services and lots of restaurants around — so I can explore on my own. If you've been before, could you give me some tips on which area you went to and what your experience was like?

Thank you so much in advance! I'm looking forward to hearing your thoughts, everyone! 🥰
