My question is how does Life Extension’s Skin Restoring Phytoceramide with Lipowheat maintain skin hydration? Are there any other benefits that this product provides?

Ceramides play a central role in preserving healthy-looking skin. They are an important lipid component of the skin’s membrane, where they provide protection from the elements and lock in moisture.In fact, they make up 35%-40% of the binding matrix that maintains moisture balance and protects the skin’s surface. The problem is that the body’s production of ceramides declines with age.
The ceramides that young skin naturally produces to retain its supple appearance are identical to those present in wheat … which is why wheat-derived oils have been used topically for centuries as a natural moisturizer. But you can’t get enough ceramides from topically-applied wheat germ oil to have a long-term impact on your skin’s appearance. And they don’t appear in sufficient concentration in your diet.
Both in vitroand in vivo studies demonstrate that the moisture content of the stratum corneum (the top layer of skin, over the epidermis) in aging humans is decreased. In maturing individuals, the stratum corneum is also susceptible to inflammation and infection. Research shows that aging skin also suffers from reduced structural integrity due to lower lipid content.
Studies confirm the decline of the ceramides, possibly due to a decline in enzyme activity that helps to deliver ceramides in usable form to the skin. When aging skin’s ability to make ceramides diminishes, as it inevitably does, increased ceramide intake becomes essential.
For example, after three months of ingesting 200 mg a day of ceramides, a group of people reported dramatic improvement in the look and feel of their skin. These results were verified by electrochemical analysis showing that 95% of participants exhibited improved skin hydration. Better yet, all subjects who experienced itching at the onset of the study reported sharply decreased itching or complete elimination of the problem by the end of the study.
Another potential use for ceramides is in the production of sphingolipids – an important fat for healthy myelin sheaths. This could be beneficial to MS patients.
