Has anyone tried Clarins "Skin Difference"? It's a new product designed to be applied to the skin at night. It is then claimed to penetrate hair follicles overnight to soften the entire length of each whisker in preparation for the next morning's shave. It's also claimed to remove dead surface cells, and to moisturise. It costs GBP26 (I live in England) and I'd like to know if anyone's tried it, and their opinion, before spending this amount of money
