First time in Seoul for beauty treatment, where is recommended?

Hi everyone! I'm Rina from Indonesia, and I'm planning a trip to Seoul next year specifically to explore aesthetic treatments and skincare. I'm really curious about famous areas like Gangnam and Apgujeong — are there really as many clinics as people say?

I wanted to ask, for those of you who have been there, which area is the most comfortable to explore? I hear Gangnam is super bustling and has everything, but it's also crowded. And Apgujeong is said to be more upscale? Honestly, I'm a bit overwhelmed thinking about where to start.

Oh, and one more thing — where do you stay on beauty-focused trips like this? I prefer somewhere close to the clinic area for convenience, but I also want a reasonable price. Any suggestions for a good area to stay that still has access to treatment spots?

Thanks so much, guys, hope to hear from you! 🙏
