Rkane, Yes a mask prevents the masked parts from being effected by sculpting, painting, or whatever. You can paint a mask directly on any mesh with the brush by just holding down the ctrl key when in edit mode (the brush will turn from red to yellow). The only reason I suggested using an alpha mask for the lips as apposed to just painting directly on the mesh is (in this case) it is just more precise. Masking and Alphas are very powerful tools in Zbrushlearn all you can about them. Hell you can easily make tight fitting clothes by just painting a mask on a figure then delete the masked areas and inflate the remaining mesh. Or you can get really crazy and do stuff using alphas and masking like the artist Meats Meier does (link). Have fun, SWAMP Edited to make sure the image in the link is not on Rendos newest hate list, and add the Nudity flag.
