Hey international ladies, which area in Seoul do you love the most for beauty treatments?

Hi everyone, this is Hong, and I'm planning my first trip to Seoul to get some under-the-skin treatments and a haircut. I've heard that Gangnam and Apgujeong are areas with tons of spas and beauty clinics, but I'm still feeling a bit lost. For those of you who have traveled here before, could you share which areas offer plenty of options and are also easy to get around?

Also, I'm wondering about accommodation. Should I stay close to these beauty hubs, or is it okay to stay a bit further out? I'm worried about spending too much time and money on taxis if I stay too far. My budget is pretty average, not super high, so I'm looking for reasonably priced accommodation too.

Has anyone tried exploring multiple areas during their beauty trip? Should I "tour" different neighborhoods, or is it better to focus on one area to streamline things? Thanks in advance, ladies! I'm really looking forward to your advice from those who have been there! 💕
