Waking Up With Caffeinated Soap

Shower Shock is a peppermint soap infused with caffeine designed to energize you through your skin. While the company claims it provides a morning boost, experts doubt enough caffeine absorbs through the dermis to actually wake you up.

This product relies on the idea that your skin can soak up caffeine as efficiently as your digestive system. In reality, the molecules likely do not penetrate the skin barrier in significant enough quantities to create a buzz. Most users find that the scent provides a pleasant zing, but it certainly won't replace a standard cup of coffee. It serves as a fascinating example of how creative marketing can sometimes outpace actual human biology.
