I'm heading to Seoul soon, ladies! Any skincare recommendations or beautiful spots to visit?

Hiii everyone, I'm Uyen, and I just booked my flight to Seoul for next month, and I'm so hyped! I've wanted to experience K-beauty treatments that are only available in Korea for a long time, not just buy things online. Can anyone recommend some cool areas to check out? I've heard Myeongdong and Gangnam have tons of skincare clinics, but I'm a bit lost on which one would be best for me.

I have oily, acne-prone skin, so I'm looking for treatments specifically suited for this skin type. Has anyone tried any products or services that they found truly effective? I'm not sure where to start, so I'm really hoping for some practical suggestions from you all. I've set aside a preliminary budget but would also like to know what a reasonable amount to prepare would be.

Thanks in advance, everyone! I'm really excited and looking forward to your advice, ladies 💕
