Dermatology clinic in Gangseo-gu, Seoul

I'm not looking for expensive treatments or procedures, so I think it'll be similar wherever I go. But is there a dermatology clinic in Gangseo-gu that you can recommend?

I want to get a mole removed that is about 2.5mm in size on my cheek and get acne removed and scars taken care of, but I'm not sure if the price is proportional to the skill level.
