About to fly to Seoul for the first time, does anyone have any tips for me? 🛫✨

Hey everyone! I'm Tuyến, and I'm heading to Seoul in two weeks, which feels like ages away, haha. This is my first time in Korea, so I'm both excited and a little nervous. I'm planning to explore beauty experiences there, but I'm worried about getting lost or feeling overwhelmed because I don't understand the language. Can anyone suggest areas and skincare/aesthetic experiences I should check out? I have pretty sensitive skin, so I'm looking for places that seem safe and professional.

I've heard Myeongdong and Gangnam have some pretty famous spots for this, but I'm not sure where to start. Has anyone tried deep cleansing facials or anything similar? I have a budget in mind for treatments, but I'm not entirely sure yet, hehe. I also wanted to ask if there's anything I should prepare beforehand, or if I should just go and figure things out on the spot?

Anyone have recent experiences? Your feedback would really help me prepare mentally and with my plans. Thank you all! 💕
