Do any of you have experience with beauty tourism in Seoul? Where are the best places?

Hi ladies! My name is Lien, and I'm from Vietnam. I'm planning a trip to Seoul next year to try some beauty and aesthetic services. I've heard that Gangnam and Apgujeong are quite famous for this, but I'm not sure which area is more suitable.

I'd like to ask those of you with experience in beauty tourism in Seoul – which areas do you usually stay in? Gangnam, Apgujeong, or are there any other good areas? I want a place near aesthetic clinics, and also convenient for shopping and eating.

Regarding accommodation, which Airbnb or guesthouse areas do you recommend? I don't have a super high budget, so I want to find something reasonably priced. And I'm not sure how long I should stay – how many days do you usually stay on a trip?

Thank you in advance! 🙏
