S.L. Hsia, Ph.D., director of the Transdermal Delivery/Cutaneous Biology Laboratory and principal investigator of the research, said, “It is amazing that a benign compound, CoQ10, can cause the cancer cells to selectively kill themselves without harm to normal cells. Moreover, we have a novel topical delivery system that offers cancer patients an improved quality of life with a boost of energy.  Indeed, our team looks forward to one day bringing the benefit and hope of this technology to many cancer patients.”

I say "WOW"!
