My first time going to Seoul is really trying Korean skincare! Does anyone have any recommendations?

Yay!!! I'm so excited because I'm going to Seoul in two weeks! 🇰🇷 Ever since watching videos and reading about Korean K-beauty, I've really wanted to try the products, browse my favorite skincare stores, and see what they're really like.

Has anyone tried any of the facial treatments there? I'd love to try them but I don't know where to start. What are the prices like? I've set aside a budget but I'm not sure if it's enough 😅 And do I need to book in advance or can I just walk in?

Does anyone have any must-try products? And anything else interesting at the place? Thanks in advance! 💕
