Have just been reading this blog post which states that nearly all of Creme de la Mar's super expensive ingredients are found in Nivea, the humble moisturiser in the blue tin! Imagine that if something that is about 1.50 could rival the £100's a time pot!!??
I reckon its got to be worth a try, will report back.
Going to look for similar, "buy this for pennies and look amazing" type products now :)
