Our skin is waterproof because of fat

Resistant - this property is a skin on which we usually do not pay attention. But it is terrible to imagine what would have happened if it were not so! For example, from rain dabbing not only our clothes, but also the skin. And what happens to people after a bath? ..

Waterproof skin provides a thin layer of fat between the extremes of its layers. The molecules of fat (lipids) are hydrophilic (vlagosobirayuschuyu) "head" and two hydrophobic (moisture repellent) "tail". Lipids are located under the top layer of the skin in a staggered manner, ensuring reliable water resistance skin both outside and inside.
