7 . The method of claim 1 , wherein the pharmaceutical composition comprising CoQ10 is administered in the form of a CoQ10 cream at a dosage of CoQ10 between 0.01 mg/cm 2 and 5 mg/cm 2 .

8 . The method of claim 1 , wherein the pharmaceutical composition comprising CoQ10 is administered with a second composition comprising an additional agent.

9 . The method of claim 1 , wherein the pharmaceutical composition further comprises an additional agent.
