Hello i made a human with zspheres when i press a, i go into adaptive skin mode and i can sculpt but i am not happy with my sculpt and want to start over but with the same zsphere how do i do that? thank you
Add another ZSphere to the figure or delete one. Then preview the mesh.
My recommendation is to add one. After previewing the mesh you can then delete it immediately. Your sculpting will not revert.
Basically, whenever you add or remove ZSpheres you force a new mesh calculation. This automatically deletes all sculpting and polypainting since it’s based on a point order that no longer exists.
i have tried that already, but that does not work for me the way i want it (yes it does recalculate the mesh, but not in the way it did first) here are a few screenshots to show what i mean
when i press a to go into preview mode, he doesn’t smooth it very good 
when i create a new zsphere testmodel, and i press a to go into previewmode he smooths it the right way
