When I was working in Seoul last year
I consistently went 2-3 times a month for skin tone and skin texture care.
Among the factory-style dermatology clinics I had tried, I think this one was cost-effective and pretty good.
However, since there are a lot of people, even if you make a reservation the waiting time gets delayed, and the aftercare is a bit lacking.
But if you are mainly looking for cost-effectiveness, I think it is fine.
