The Skin And Phytoceramides - How They Work Together The outermost layer of mammalian skin is known as the stratum corneum. It acts as a barrier and protects the inner cellular structure from external stresses. In so doing, it helps in keeping the skin protected from factors such as excessive transcutaneous water loss. The cells of the outer layer which are made up of ceramides and conrneocytes are what work in accomplishing this very important function by creating a barrier. Any disruption in this barrier through physical trauma arising due to conditions such as eczema or simple aging will compromise its functional ability. The result of such compromise includes decreased skin elasticity and increased susceptibility to infections as well as increased water loss. All these factors speed up the formation of fine lines and wrinkles at the corners of the eyes and mouth in addition to creating a dull skin texture. They are the signs that will easily tell the age of an individual. People dread the formation of these cosmetic changes and many, especially women have gone to great extents to work out a solution to fighting the signs of aging. The Ceramides Solution The ceramides responsible for skin health are produced naturally in the body. The amount decreases with age. Plants contain protein compounds with the same kind of structure; almost identical to what humans have. Since they are plant derived, they are referred to as Phytoceramides. Like the ceramides found in the human body, the Phytoceramides aid in creating a protective barrier within the epidermis.
