Finally going to Seoul! Any sisters have recommendations for must-try beauty treatments?

Hey everyone! I'm Tao, and I'm finally heading to Seoul for a business trip next month. I want to take this opportunity to fully experience Korean beauty and skincare. I've heard that Seoul has a really strong medical aesthetics scene, and many local skincare brands are super popular. However, I'm a skincare novice and don't really know where to start.

My skin is sensitive and combination type, and lately, I've been wanting to improve my pores and uneven skin tone. Have any of you been to Korea for skin management or other treatments? I'd love to understand the general process and what preparations I need to make beforehand. Also, which areas in Seoul are concentrated with beauty clinics?

Additionally, I'd like to explore local skincare shops and see if there are any products suitable for my skin type. I would be so grateful for any personal recommendations you have! For example, which treatments are worth trying, or are there any things I should be mindful of. Looking forward to hearing everyone's experiences!
