Is there a good dermatology clinic near the Shinchon Hyundai Department Store?

I live in Gyeonggi Province, but I think Seoul is a bit better, and conveniently, there are good transportation options directly from my house to Seoul.

The dermatology department... Severance is a very large hospital...

Are there many dermatology clinics near Yonsei University, Hongdae, and Ewha University? Is there a cost-effective dermatology clinic?

As I get older, I find myself worrying about dull skin for no reasonㅠ

Especially with melasma... I feel like it's getting darker gradually.

Cream and essence don't seem to improve itㅠ
