Phytoceramides Rejuvenate Skin and Deter Eczema, Dermatitis

phytoceramides and skin issues

Researchers are increasingly finding that internal consumption and topical application of phytoceramides have multiple health-promoting effects upon the skin, including healthier skin hydration and fewer skin infections.

Clinical studies document phytoceramide effects on the skin

The use of wheat-based, or wheat germ oil-based creams and supplements for drying, aging skin has now been clinically tested. For example, French researchers tested 51 women who were between 20 and 63 years old with a wheat oil extract for three months. Half the group was given a placebo and the other half was given 350 milligrams of the wheat oil extract.

The extract was given internally only.

After the three months, there was a significant improvement in skin dryness and redness among the wheat oil extract group. The extract also resulted in reduced roughness and other signs of dryness. The wheat oil extract group saw an increase of 35 percent in skin hydration while the placebo group showed a mere one percent.

Eczema and dermatitis helped

This is balanced by a study by researchers from Australia’s Murdoch Children’s Research Institute at the Royal Children’s Hospital in Parkville. Here 10 infants with a family history of eczema and skin allergies were given a cream containing phytoceramide oil for six weeks. The researchers found the children responded well to the cream and had a reduction in eczema. For a couple of the children, eczema occurred only in places where the cream was not applied.

Phytoceramides help protect against UV damage

Research from India’s Council for Scientific and Industrial Research found that ceramides help protect the skin from damage from UV-radiation. They wrote that ceramides provide a facility for protecting the skin cells against oxidation from radiation effects.

Research from the Charles University in Prague found that ceramides provide a double-bonding lipid membrane between and around skin cells that decrease their permeability.

Ceramides help protect against skin infections

This issue of permeability is important when considering skin infections. Nearly a decade ago research from the Medical School at the University of California at San Francisco found that ceramides regulate the skin cells’ water barrier and those with skin conditions like dermatitis and psoriasis were found to have a reduction in this barrier and lower levels of ceramides.

They also found that skin diseases also typically come with reductions in ceramide levels, often symptomized by increased levels of ceramide-degrading enzymes like ceramidase and sphingomyelin deacylase.

The researchers concluded that the application of topical ceramides will likely help prevent such deficiency. They also found that ceramides appear to inhibit elastase enzymes known implicated in causing wrinkles.

But the research such as that mentioned above showing that ceramides are significantly provided to the skin through consumption.

Natural sources of phytoceramides

There are now several supplemented forms of ceramides, both for topical and internal consumption. Good sources of phytoceramides include wheat, millet, rice, soybeans and spinach and others. Wheat germ oil contains about 6% glycolipids, of which ceramides predominantly make up. Ceramides are classified as sphingolipids, which are utilized in the body as signalling and protective fats – smart fats if you will.

Wheat germ oil can be applied to the skin as well as taken internally.

The outer epidermis layer of skin – the stratum corneum – is made up of primarily keratinocytes. Surrounding the keratinocytes is an intercellular substance made up of cholesterol and free fatty acids. Ceramides make up between 40 and 50 percent of this intercellular material. Ceramides make up the largest portion of lipids among healthy skin cells.

I had just spent the last two hours explaining how diet, sleep and other lifestyle choices create health problems and how changes in these, along with certain herbal medicines and other natural strategies can radically yet safely turn ones health around. As I drove home that night, I realized I needed to get this knowledge out to more people. So I began writing about health with a mission to reach those who desperately need this information. The strategies in my books and articles are backed by scientific evidence along with wisdom handed down through traditional medicines for thousands of years.” Case connects with the elements by surfing, hiking and being a beach bum.
