I recommend a sheet mask that helps get rid of pimples.

You say you get pimples even after taking off your mask?

In that case, I recommend the EasyDew EX DW EGF Hydration Mask from Daewoong Pharmaceutical.

It provides both hydration and soothing at the same time, and it is a mask pack I always use as an emergency remedy whenever my skin is red and irritated like a volcano. You should give it a try too.
