First time in Seoul! Does anyone have any Korean skincare tips?

Hello! My name is Ice, and I'm going to Seoul for the first time next month 🥰 I'm so excited! Since I started researching, I've learned that there are many skincare and natural home remedy sources there, and I think there will be K-beauty experiences I should try.

I already love skincare, but when I go to Seoul, I want a spa-like experience or treatments that make my skin radiant. Does anyone have recommendations on what I should try? Are there any must-try spots that are good for walking around or that I can visit after a long day?

And what about authentic Korean products? Are there markets where I can buy skincare, or do I need to go to a self-service department store? I'm also a bit unsure about the budget. I'd really appreciate some real information. Thank you 😊
