I'm going to Seoul next month. Any skincare recommendations from the ladies?

Hey everyone! I'm Jing, and I'm finally saving up enough vacation time to go to Seoul! I'm so excited 😍 I love researching Korean makeup, and I want to take this opportunity to experience the local skincare culture. I've heard Seoul has many different beauty salons and clinics, but this is my first time there, so I'm a little unsure where to start.

I mainly want to ask you guys: are there any skincare experiences that are really worth trying? Like skin management or face mask treatments? My skin is combination to oily, with some fine lines and enlarged pores, but not too serious. I'm not looking for anything major, just to experience the local Korean skincare philosophy and learn something.

Also, I'd like to ask if I need to make an appointment before visiting the clinics? I've heard some places offer consultations, but I'm not sure about the process. Has anyone been to any clinics and could share their experience? I'm still considering my budget, but I'm looking for something with good value for money. Looking forward to your suggestions!
