Where should you stay for your Seoul beauty trip?

Hi everyone, it's Mizuki! I'm planning a beauty trip to Seoul this fall, and I'm wondering which area would be best to stay in.

I've heard that Gangnam and Apgujeong have a lot of cosmetic clinics, but what's it really like? Also, if I were to stay in those areas, are there other fun things to do? Honestly, I'm worried I might get bored just hopping between clinics... haha.

This is my first beauty trip to Seoul as a foreigner, so I'd love to hear about the experiences of others who have come here for similar reasons. If you have any information about which areas are easy to get around, have a good atmosphere, or anything else, please let me know. I don't have a clear idea about budget or access yet, so any advice at all would be greatly appreciated!
