According to Philosophy\'s own web site http://philosophy.com/moreinfo.php?upc=604079002486&ctg=metaphysics&grp= falling+in+love&fnc=best+sellers&SID=i3c7b4d22efa1 0d# it contains unspecified pheromones and is meant to help increase the woman\'s sense of well being and thus make her more attractive. Seems like a good marketing strategy to me since women buy far more in the way of fragrances then men do and they\'ll wear it make themselves feel good. It is unscented though so they\'ll likely buy Philosophy perfume like \"Soulmates\" as well. I don\'t feel threatened beside I just got some SOE.
