I recommend Mielle Clinic in Yeongdeungpo-gu, Seoul.

This is Mielle Dermatology Clinic located at 6 Yeongjung-ro, Yeongdeungpo-gu, Seoul.

The medical departments are family medicine and dermatology.

It is 140m from Exit 5 of Yeongdeungpo Station.
Sunday is a regular holiday every week
Our office hours are from 10:30 to 20:00 from Monday to Friday.
I liked that they gave me good advice and didn't recommend unnecessary procedures.
I had the impurities removed and it was good.
