sculpt smoothing a cylindrical shape

does any1 know if there is a way to smooth a cylinder with the sculpt tools. for example if i work on a hand and it has lost too much its constant shape, and i would want to recreate its smoothed cylindrical shape?
this would be like in real sculpturing when you roll a material/plasticine in your hand.

the only way i could think of is to use simplfy brush, then smooth and then rework its shape.

Smooth brush with some radial symmetry. This would only work if the area you wanted smoothing lies along one of the major axes.
