Going to Seoul next month, any suggestions for a worthwhile skincare treatment?

Hello! I'm Bella from Indonesia, and I'm super excited because I'm going to Seoul next month for vacation! This will be my first time exploring the beauty scene there, and honestly, I'm a bit overwhelmed by the sheer number of choices, hehe.

I really want to try some skincare treatments that might be more affordable or better in Korea than here. I have combination skin that's a bit sensitive, and I'm trying to address some concerns. Has anyone tried a particular treatment in Seoul and really seen results? Or are there any areas/districts you recommend for skincare clinics?

Also, I'm curious about shopping for skincare products—is it worth it, or are the prices similar to online stores? Hehe, sorry for the many questions, I'm just excited and want to prepare as well as possible to get the most out of my trip!

Thanks so much if anyone would like to share their experiences or tips! 💕
