When going on a beauty trip in Seoul, should you go to Gangnam or Apgujeong? I need some advice!

Hello friends! My name is Ariun, from Mongolia. I am planning to go on a beauty trip to Seoul later this year. Actually, this is my first time going there for this purpose, so I am a little confused.

One of my main questions is - Gangnam or Apgujeong? Which one is better to stay in? I heard that there are many beauty clinics, massage parlors, and places to buy beauty products. But I don’t know which one is more convenient and more comfortable. Also, are the hotel prices different?

If you have been to Seoul for this purpose before, please share your experience! I am looking for places with translators and friendly service for foreigners. Or are other districts also good?

Thanks in advance! 💕
