Ever wonder how a substance called keratin helps healthy skin to retain its natural level of moisture? Most skin care products contain hydrolyzed keratin, but not the product that qualifies as the best moisturizer for very dry skin. The best skin moisturizer is unlike any previous moisturizers. That product contains keratin that has undergone a process known as solubilization.

Why should it matter what process has been used to add keratin to a skin care product? As a protein that is found throughout the body, shouldn't any type of keratin enhance the structural composition of a skin cell? Why does one particular method for processing keratin allow a certain skin care product to be the best moisturizer for very dry skin?

Anyone looking for a best skin moisturizer needs to understand just how keratin functions in the skin. Not all keratin displays the ability to moisturize the skin. Only something called "functional keratin" has the ability. Are there skin care products that contain functional keratin? Yes, there are such products.

Functional keratin is a key ingredient in a natural substance, a substance that has been extracted from the wool of New Zealand sheep. Manufacturers place that substance through a process known as solubilization, before adding it to a unique product for treatment of dry skin problems. That process, unlike hydrolization, allows the keratin to be readily available to the skin.

In the past, the makers of skin care products obtained keratin from the hooves, horns and feathers of various animals. In order to extract keratin from those animal parts, manufacturers had to subject the keratin to high temperatures and to acid. After undergoing such treatment, the keratin in the final skin care product did not remain fully available to the skin.

Today, however, a new method for the extraction of keratin has allowed manufactures to obtain keratin from the wool of New Zealand sheep. This new process allows the extracted keratin to become part of bio-active polymers. Such polymers make it easy for the skin cells to access the moisturizing qualities of keratin.

In fact some who have used the skin care product with this new type of keratin have called it "liquid skin." They have seen first hand just how effectively that keratin can heal dry skin. They support any effort to declare the product with this new type of keratin to be "the best moisturizer for very dry skin."

Scientific studies back-up all the testimonials on the best skin moisturizer. Scientific studies have shown that when keratin is made fully available to the skin, then it stimulates the production of new skin cells. It provides the skin with important minerals-zinc and copper. When skin contains an adequate amount of such minerals, then it is better able to heal itself.

Is it any wonder that so many who have spent much of their lives struggling to heal dry and chafing skin have welcomed this new, patented process? They appreciate the fact that, due to this new process, there is now a skin care aid that taps into the natural, moisturizing function of keratin.
