Adult epidermis is the body's front line of defense and serves as an effective barrier that prevents dehydration due to loss of body moisture, poisoning due to absorption of harmful substances, and systemic infection as a result of the penetration of microorganisms. The epidermal barrier resides in the outermost layer of the epidermis (stratum corneum). In utero, the fetus has no need for an epidermal barrier, so this outer layer does not begin to develop before week 24 of pregnancy. From week 24 there is a steady increase in the number of layers of the epidermal cells and in thickness, until full skin development in the 34th week of pregnancy.

A full skin barrier protects the body from the outside in – blocks the invasion of harmful factors and sunlight, and from the inside out – protects against water evaporation and moisture loss from the skin. Evidently, although the environmental conditions are constantly changing, the conditions inside the body remain pretty much constant, thanks to the epidermal barrier.

The epidermal barrier is the outermost layer of the skin, which in the past was thought to consist of dead skin cells that have no meaning or purpose. In recent years, new scientific discoveries indicate that the components of these cells and the substances between them (fatty molecules – lipids, the main of which – ceramides) together, make up the reverse line of defense of the skin – that is, act as a buffer and prevent the "escape" of essential substances from the body out.

Structure of the epidermis

All the cells that make up the epidermis begin their sorting process in the basal layer as dead skin cells called corneocytes. In the sorting process they are pushed up to the surface and their structure changes. Finally, they reach the outermost layer, and from there they fall off.

Foundation cells on the surface are stacked like a brick wall with 3 necessary epidermal lipids: ceramides, cholesterol and fatty acids that form the network or border between the cells. A normal epidermal structure will be dense (rich in a high amount of corneocytes) and strong (rich in a high amount of epidermal lipids).

What can cause damage to the epidermal barrier?

In various situations the function of the epidermal barrier is disrupted and as a result, the epidermis suffers from a defect in function and appearance. 

  • Genetics: Skin in which the essence of the epidermal barrier has a functional defect. Lack of complete blockage leads to over-penetration of tiny particles, such as various allergens. Such skin will react with excessive irritation to exposure to particles such as active skin care products, odor and color molecules, etc. In fact, such skin will be defined as "sensitive skin".
  • Disease conditions: example – skin asthma, eczema, etc. 
  • Age: With age the function of the epidermal barrier becomes sub-optimal. 
  • Post-trauma to the skin – intentional (invasive cosmetic treatments) or unintentional (after sunburn): In such cases the epidermal barrier usually manages to regenerate but during the restoration period there is a high sensitivity of the skin to external damage due to damage to the epidermal barrier.

The most immediate and noticeable effect of impairment of the function of the epidermal barrier is manifested in the loss of moisture, or the inability of the skin to preserve the applicability of its water. As a result, the level of inflammation of the skin increases and it becomes irritated, sensitive, red, loses its elasticity, volume and radiance.

But more than that, even when there are no visible skin effects, leading innovative studies have shown that in a state of decreased function of the epidermal barrier, a high level of inflammation was measured in the bloodstream itself. That is, the health of the epidermal barrier has a general effect on the health of the skin and body.

How to maintain or repair the epidermal barrier?

In order for the epidermal barrier to function properly, the level of moisture and the amount of fatty components inside it are important. About 50% of the fatty components are molecules called ceramides. That is, the essence of healthy skin is to maintain a sufficient amount of ceramides and moisture. When the skin is balanced with a restored and healthy epidermal barrier, the skin cells in the deeper layers function as expected, the rate of molecule production – necessary for healthy, thick skin with a uniform and vital appearance – by the skin cells themselves rises and approaches young skin levels.

A word from the doctor – about SUPCERAT™, a revolutionary active complex for restoration of the epidermal barrier

With a deep understanding that as high quality as are the active ingredients known in the cosmetics industry today, they have no meaning without a healthy epidermal barrier that keeps them inside the skin tissues and prevents them from evaporating – we set out on a long and challenging journey with one purpose – to find the combination of substances that will restore the epidermal barrier and give it optimal effectiveness that will even affect the function of the deeper skin tissues.
We partnered up with the long-standing and technologically leading ASHLAND laboratory in the field of chemistry and materials, in the south of France. Together we performed laboratory tests on skin tissues to examine, repair and improve – and finally, to reach the optimal result. A holistic combination of active ingredients: ceramides, peptides and one super-fruit that is much more than just a powerful antioxidant.
Laboratory results were no less revolutionary:

The SUPCERAT™ has been clinically proven to increase the amount of self-production of hyaluronic acid skin by 64%, in just 24 hours

The SUPCERAT™ has been clinically proven to increase the amount of self-production of epidermal lipids (which make up the structural material of the epidermis) by 185% (i.e. the amount almost tripled), in just 48 hours

The SUPCERAT™ has been clinically proven to increase the concentration of ceramides in the upper layers of the skin by 55%, in just 24 hours

The SUPCERAT™ has been clinically proven to significantly increase the concentration of the enzyme Claudin (a protein responsible for the density of the epidermal barrier) in the upper layers of the skin, to prevent the evaporation of moisture and the penetration of free radicals into the epidermis

The MAHUT series is built around its core component, the SUPCERAT ™, and all products in the series contain the innovative complex in its optimally proven concentration.
