Going to Seoul next month, what skincare & aesthetic experiences should you try?

Hi everyone! I'm Tiara from Jakarta and I'm so excited to finally be going to Seoul next month. I've been wanting to explore the K-beauty scene for a while, especially the skincare and aesthetic treatments, which are said to be great there.

I'm pretty diligent with my skincare routine at home, but I really want to try a facial or treatment that might not be available in Indonesia. From what I've read, Seoul has many popular clinics and skincare studios. But I'm confused about which ones are worth it and suitable for my combination and sensitive skin. Does anyone have any personal experiences? Which treatments were truly memorable or made a difference for you?

Also, any tips on the best areas for skincare shopping and clinic-hopping? I'm planning a week-long stay and want to maximize my time. If anyone can share their experiences or recommendations, I'd really appreciate it! Budget-wise, I'm already prepared, but I don't know what to expect for typical treatment costs there. Thanks!
