why Human skin is withered?

The skin of a person is a lot like a sponge that can retain them even when it is hygroscopic. Group of Australian researchers have discovered the secret of the skin, that's why our skin is shrinking, but does not dissolve when wet Myfanwy Evans of the Australian National University in Canberra and colleagues reported their findings in the journal Journal of the. Royal Society Interfaces.
Evans said that the bath water, the outer layer of skin, called the stratum corneum growth. Cause wrinkles on the skin. Apparently the fingers and toes. The fingerprints will be expanded as well. Previous research by other researchers that have studied the structure of the stratum corneum can be expanded in the form altogether. With water absorption. However that does not explain why the skin did not melt. Or dissolution, as well as other substances. Easy to melt on the structure of the expansion.
Evans has created a computer model of the stratum corneum of the skin effect and can help explain such phenomena. By now she has just graduated with a Ph.D. Under the view of Professor Stephen Hyde.
Modeling has shown that the structure of the skin is hard and can grow in the water. The building features a three-dimensional lattice structure of the stratum corneum keratin filaments twisting strenuously. Then weave themselves in a line of three dimensional keratin fibers that are woven together to act like a sponge. Shapes that can be placed in the water to absorb. Strands of keratin fibers are very strong. It allows the skin to expand and increase the quantity of water that can be absorbed.
However the key is that the skin growth. Where the building is connected to the keratin fibers remain. I do not fall off. This allows the structure of the skin is very stable. So when we are immersed in the water long. Even for the 24 hours it will not damage the skin.
