Most Expensive Soap

If you can’t stand using the same soap as the plebeian hordes, then Plank—a producer of yoga-themed products—has the soap for you. It’s called Cor and it’s the world’s most expensive soap.
Among its ingredients, Cor has chitosan to even out skin tone, sericin—a silk extract—to trap moisture and provide UV protection and four types of collagen to help maintain skin structure. Silver, a known antibacterial agent, is what makes Cor the most expensive soap in the world.
On the other hand, it’s questionable (at best) that any of that crap can really help your skin. Chitosan and sericin will rinse right off and collagen is more useful in deeper layers of skin. The silver is, of course, proven, but there are much cheaper antibacterial soaps out there.
Cor retails for $125 for a 120 gram bar.
