Trying out K-beauty in Seoul! Who's got experience?

Hi! My name is Nomin, and I'm from Ulaanbaatar. I'm planning to visit Seoul in a few months. This time, I'm looking to explore K-beauty, wellness procedures, and popular trends. I've already browsed many websites online, but real people's opinions and experiences are incredibly valuable.

Can anyone recommend K-beauty doctors or clinics in the Seoul area? Have you had any positive experiences with specific products or procedures there? I'm particularly interested in different perspectives, especially for those with sensitive or acne-prone skin.

While I understand that choosing a clinic and doctor, as well as planning treatments, involves many factors and isn't always straightforward, I'm keen to learn from others' good experiences. What are the wellness options available in Seoul? I'd love to hear your advice!
