What's the most effective way to "smooth out" faces/vertexes around an area so they all match? WITHOUT completely fucking up the overall shape of the mesh? I just can't get vertexes to look good near each other after joining some pieces onto a body mesh. 
I've already tried
-subdivide+smooth (didn't seem to help at all)
-smooth tool in sculpt mode (it re-shapes the verts okay, but it also reshapes WAY too much of the overall mesh and really fucks up the overall shape)
