Once we have applied the Skin and Armature modifiers, we are left with an almost ready-to-use base mesh; what we need to do now is clean the possibly overlapping faces and whatever other mistakes were made by the Skin modifier.
Be careful not to be confused by the previous recipe, which was meant only as a possible example; we didn't actually use the Skin modifier's Armature to change the pose of the base mesh.
Let's prepare the mesh and the view:
Sometimes, depending on the topology created by the Skin modifier, you may not be able to make a single clean loop cut by the Ctrl + R key shortcut. In this case, still in Edit Mode, you can press the K key to call the Knife Tool, left-click on the mesh to place the cuts, and press Enter to confirm (press Shift + K if you want only the newly created edge-loops selected after pressing Enter). This way, you can create several loop cuts, connect them together and, if necessary, move and/or scale them to the middle along the x axis.
In fact, you can do the following:

.Well, in our case, everything went right with the Skin modifier, so there is no need for any big editing of the mesh! In effect, it was enough to delete the first Mirror modifier (that we actually used mostly for visual feedback) to get rid of all the overlapping faces and obtain a clean base mesh:
In the preceding screenshot, the base mesh geometry is showing with a level 1 of subdivision; in Edit Mode, it is still possible to see the low-level cage (that is, the real geometry of the mesh) as wireframe.
There are a couple of triangular faces (that, if possible, we should always try to avoid; quads faces work better for the sculpting) near the shoulders and on the feet, but we'll fix these automatically later, because before we start with the sculpting process, we will also apply the Subdivision Surface modifier.
To obtain a clean half-body mesh, we had to delete the first Mirror modifier and the vertices of the right half of the mesh; to do this, we had also added a middle edge loop. So, we obtained a perfect left-half mesh and therefore we assigned again a Mirror modifier to restore the missing half of the body.
