Biological Ingredients Moisturize Dry Skin

For thousands of years our ancestors used oils for improving the appearance of their skin. But since 1920, the cosmetic industry begun to spread the idea that oils were bad for the skin and promoted the use of oil in water mixed with detergent as moisturizing creams. This was similar to fallacious campaigns to get women to replace breast feeding their children and instead feed them artificial infant formulas that could be sold for a profit. In Asian countries, oils are still preferred to improve skin health.
Cosmetic cream or serum moisturizers are made with a variety of low-cost oils and water-soluble chemicals that humidify and loosen the skin's layer of outer protective proteins and also cover the skin with fats that block the skin for a while and thus obstruct water loss. They provide moisture to dry skin for a short period of time but affect the skin's defensive properties against bacteria and viruses. These moisturizing creams are a mixture of oil and water plus stabilizers, emulsifiers, preservatives and other chemicals.
How To Prevent Dry Skin
Most of these products retard the healing of irritated and injured skin and make the situation worse by impeding normal skin repair and increasing skin inflammation and thus damage in ways similar to skin irritants.
What really works is to shield the skin surface and to cure the skin from within, by supplying the skin the nutrients and an environment in which natural skin repair can happen.
Virtually all moisturizers and emollients offered by the large skin care enterprises marketing them contain high concentrations of detergents and detergent-like chemicals, ignoring 40 years of scientific evidence that these detergents damage the skin and degrade the skin's natural defensive and protective abilities. Also, many of the dyes and optical diffusers that are included in cosmetics to give the appearance of healthy natural skin are very harming to the skin.
Research and Biological Treatment Benefits
Another mistake is to add to skin creams certain lipids that occur naturally in the skin like ceramides (especial amine fatty acid structures), free fatty acids (fatty acids not in triglyceride or phospholipid form), and cholesterol, expecting that this replenishes skin lipids and improves skin health. However, latest research has found that adding biological skin fats and lipids to skin creams causes a reduction in the skin's natural production of skin fats and lipids so that, in a few weeks, the skin is in worse shape than before.
Dry skin is caused by two events:
(1) damage to the skin's protective barrier which causes excessive water loss through the skin, and
(2) reduction in the proportions of the skin's water-holding sugars and proteins: the proteoglycans and glycosaminoglycans (GAGs).
Proteoglycans (PGs) are proteins linked to glucose chains named glycosaminoglycans (GAGs) and are vital elements of connective tissues. They play an important role in regulating the structure and controlling the functions of the skin.
The timely renovation of proteoglycans influences the development and differentiation of cells. Wound healing also depends on the level of PGs which if not adequate leads to abnormal scars, and thus play an important role in avoiding keloid and hypertrophic scars.
Biological Ingredients Moisturizing Your Skin
When the skin loses glycosaminoglycans the skin becomes flaccid, both on the face and body. GAGs hold water and fill most of the intercellular space between collagen and elastin proteins. They perform a critical role as shock absorbents and provide binding, hydrating and swelling pressure to cell tissues. Meanwhile, they enable the skin to withstand compression forces and thus prevent tearing of the deep layers during times when our skin is under more pressure.
For the best skin care you should use products that help repair the skin barrier and promote the synthesis of proteoglycans and GAGs.
