Our skin has a protective top layer, called the stratum corneum, made of protein and fats that absorb water. A primary function of the stratum corneum is to protect the underlying tissue from environmental injury. In areas that experience high mechanical use and friction - such as the palms, fingers, soles, and toes - the stratum corneum has evolved to be thickest and hence most protective. As a result, these areas of the skin can absorb the most water. They also have less room for expansion and therefore tend to wrinkle most when they get wet.
