Getting ready for Seoul! Anyone have any must-try K-beauty tips?

Hi! My name is Kaew, and I'm going to Seoul for the first time next week. I'm so excited! 😆 I want to fully immerse myself in K-beauty and skincare. I especially want to try some of the famous spa and facial treatments in Korea, but I don't know where to start.

Has anyone been to Seoul before? Did you try anything that you really loved? I have sensitive skin, but I want to try new things because many people say treatments in Korea are very effective. I'm just not sure where to find a good clinic and how much to budget. Does anyone remember?

I'd also like to know if there are any skincare products or treatments for sensitive skin that are worth trying? I'm waiting for your recommendations! Thank you! 🙏✨
