I'm so excited for my first trip to Seoul! Can anyone recommend some skincare experiences?

Hi everyone! I'm Jing, and I'm finally heading to Seoul next month. I've always wanted to experience Korean skincare and medical aesthetics firsthand. Honestly, I'm a bit nervous and excited because there's so much information online, and sometimes it's hard to know what's reliable.

My skin is sensitive and combination oily. Recently, I've been looking into gentle hydrating and barrier-repair products. I've heard Seoul has many skincare experience stores, so I wanted to ask where everyone has been. I'm not looking for any major treatments; I mainly want to try different skincare programs and products and get a feel for the local professional skincare services.

I'm also a bit curious about medical aesthetic treatments, but I'm still in the information-gathering phase and would love to hear real experiences from seasoned members. For example, what's the consultation process like, how do doctors communicate, and other details like that. Has anyone been able to share their experiences in Seoul? Especially regarding how to find reliable places and what to watch out for... Thanks!
