not claim to, but one site I was looking at stated that the caffeine was absorbed through the skin and therefore did reach the blood stream and acted as a stimulant. They were wanting to claim that when it was used in a bar of soap, it worked as a "wake up" like drinking coffee does. These people were not claiming that it helped cellulite or promoted youth, just that it gave the body a little kick to get going in the morning or whenever. Do you think that is possible? I know it is a fad and most likely a bunch of bull, but do find it very interesting still. Thank you for the info. I do wonder if it could be harmful in certain cases. One site I looked at had a warning label on their soap that it should not be used by pregrant women or people with high blood pressure. I wonder if that also is part of the sales pitch? Thanks again, Soapymomma
