I go to Salons for skin brightening Treatments and have always used skin miracle professional Treatments..Now I have seen they have come up with Retail size too..They are also selling something called Argan Oil..Has anyone used Argan oil before?? Please comment!

What is Argan oil? Ive never heard of this oil before and what exactly it is used for i.e is it a face massaging oil, something you use before cleansing or something else??
