Hospital that expertly removes milia and skin tags spreading on the neck

I was worried because a few milia also started to appear around my eyes.

At some point, a skin tag appeared on my neck and is spreading sideways.

Sometimes the size gets bigger, so I'm also refraining from wearing necklaces.

Please recommend a hospital that can cleanly and effectively remove these things without side effects.

It would be even better if it were in the Incheon area.
