Each hypoallergenic facial cleanser should guarantee completion of both a primary and a secondary function. First, a facial cleanser should allow the man or woman who uses that same product to perform an effective cleansing routine. Yet a hypoallergenic facial cleanser also has a secondary role. That is the removal of dirt and grime, without the introduction of a substance that has the ability to irritate the skin.

The best facial cleansers show no evidence of a linkage to the appearance of a skin rash or other skin problems. The best facial cleansers fail to damage sensitive skin, because they do not contain a concentrated amount of certain, synthetic chemicals. Many hypoallergenics contain only natural ingredients.

A facial cleanser with hypoallergenic ingredients does not work rapidly to clear the face of grime and dirt. A hypoallergenic cleansing product carries out its function by acting gently on the skin. By acting gently on the skin, it allows the skin to retain its natural oils.

When a manufacturer prepares a cleanser, especially one that does not cause an allergic reaction, then that manufacturer often puts only ingredients from natural sources into the completed product. Such a cleanser does not contain harsh chemicals because it can rob the skin of its natural oils. Depletion of those oils can lead to the development of specific health problems.

So, what ingredients might be named on the label of a hypoallergenic facial cleanser? One of the best facial cleansers contains bioactive polymers. What are bioactive polymers, and why are they added to the product?

Bioactive polymers provide the maker of a facial cleanser with the ability to create a product that can treat the skin with keratin. Keratin is a protein, a protein that is found in all healthy skin cells. Today, one top-quality cleanser contains keratin that has been solubilized and has been used to make bioactive biopolymers. The user of this hypoallergenic facial cleanser then coats a select group of endothelial cells with the polymers, allowing the keratin to penetrate into those same cells.

Consumers should make note of the source of that keratin. The keratin that goes into the bioactive polymers comes from the wool of sheep. Now these are not just any sheep; they are sheep that have been raised on farms in New Zealand. Animals in New Zealand have, to date, shown no trace of the infectious agent that has been linked to Mad Cow Disease. In other words, such protein has been classed as a higher purity of protein.

Now, if you are planning to cleanse your face, do you want to use a product that might destroy the natural moisture in your face or do you want to use one that might expose your face to harsh chemicals or to a potentially dangerous protein? Few people would give a "yes" answer to those two questions.

That fact underscores the superior nature of a natural cleanser, especially one that has keratin, keratin made from the wool of New Zealand sheep. Now you know.
