Complex conjugate differentiation

In[1]:=D[z z*, z*]
where z*=Conjugate[z], while
In[2]:=D[z z*, z]
Out[2]=Conjugate[z] + z Conjugate'[z]
My question is: which is the best way to get as output
Should I properly define StarProduct or is there another even
straightforward solution?
Thanks a lot.

what they've done! (J.L. Picard)
