The most expensive soap in the world is called Cor by plank. 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. Cor retails for $125 for a 120 gram bar and $428 per pound.
According to the press kit it is claimed to deep cleanse the skin, minimize the appearance of wrinkles, even skin tone, fade age spots, plump, tone, hydrate, replenish collagen, heal surface skin, and provide UV protection. It can even be used as a spot treatment for blemishes. The soap is being marketed as cost-effective because it supposedly replaces the need for multiple, expensive products that target individual skin issues. In other words, think of it as the Cadillac version of Olay’s Total Effects.
To understand as to what makes this product so expensive we need to closely look at its ingredients. Silver (which accounts for the cost of the soap) is a known antibacterial agent with healing properties that speed cell growth and repair. Four different kinds of collagen are supposed to stimulate collagen formation deep within the skin. Chitosan, a natural fiber, aids cellular rejuvenation, evens out skin tone, and balances oil levels. Sericin, a soluble protein made from silk, is moisture-binding and film-forming, locks in moisture and keeps UV rays out.
This product has also received criticisms by many people. Skeptics say silver is more useful in healing wounds than in cleansing the skin, and regular soap does a perfectly good job. Others say that Sericin is not an effective UV absorber, nor is Chitsan effective in evening out skin tone, ect., because both ingredients are quickly rinsed off the skin.
As for the four different kinds of collagen, critics say they’re useless on the surface layer of the skin because their molecular structure is too large to penetrate the skin and reach the dermis, where they could do some good. To get around that problem, Cor is claimed to have a patented delivery system that is able to deposit the collagen and other active ingredients deep into the dermis layer.
It can however, not be clearly stated as to which skin types it might actually suit. Thus, its effects shall vary from person to person. It is only after using this product that a person can decide as to whether spending the huge sum of money on a mere piece of soap was worth or not.
