Jam...the fountain of youth?

I don't know how I came across this, but I am all over it...where can I get these French jams that make you look young, that's what I want to know?

According to the text a little pot of one of these jams, taken a small spoonful or two a day, will offer to your skin the moistness of youth. At the price of 7 Euros (about $9.00) for a four-ounce jar...it had better be good!
