Foreskins for the face

I recently discovered an anti-aging beauty treatment with the primary ingedient of 'Human Fibroblast Conditioned Media'. They make this with newborn foreskins. But the process, if I understand correctly, involves 'conditioning' a particular media with the foreskins. So, as collaborator Oron Catts pointed out, what is the media? Fetal calf serum? Is it a strange hybrid of cow fetus and human newborn?
