"Extract face sets" not applying smoothing

Okay so I am trying to make some different clothing for a character I downloaded. The method I used is the “Draw face sets”. I then smoothed the edges and extracted the face set. After blender switched to object mode, none of the smoothing I did in sculpt mode were transferred over. I did not change the brush settings. After researching a bit, I am still uncertain what it is and my only guess is, that the underlying mesh needs more polygons for the face mask to attach to? Below a few screen shots of what’s going on:

Looks like a shrink modifier still active for it.
