THE STRUCTURE OF THE SKIN
Derma Medical Products Group
The structure of the skin
The skin is divided into three primary layers : the epidermis, the dermis and the hypodermis .
Its functions
The aesthetic - relational : it is certainly the best known and immediate , in fact the skin also performs less well known , but fundamental to the life of the individual.protective
Functionbarrier function
Absorption function
immune function
secretory function
thermoregulatory function
sensory function
Function of vitamin D synthesis
Each of these functions is the direct result of the internal labor between the three primary layers .
Sources of
genetic heritage ;
environmental factors such as pollution , lifestyle habits , exposure to sunlight and sunlamps UVA .
The epidermis
1 germinal layer or basal layer : In this layer , there are two types of proliferative cells : the melanocyte and emidesmosoma ( cell adhesion) , flanked by Merkel cells , true sensory receptors .
2nd spinous layer , this layer can also be found in the Langerhans cells , which are important for the immune system .
3rd granular layer : here the cells are no longer called keratinocytes but corneocytes. The breaking of the cells stimulates the formation of lipids useful both as a barrier both as adhesive substance called " acid mantle " which is located above the granular layer. Its structure creates an acidic pH that prevents the passage of foreign substances into the skin and the proliferation of bacteria.
4th shiny layer is formed by cells called " clear " for their translucent appearance .
5 ° stratum corneum is the outermost and is composed of cells hard , large, flattened and keratinized , arrive at the surface from the granular layer waiting to be eliminated from the skin surface.
The dermis
It is a fabric consisting mainly of fibroblasts, collagen fibers and elastic fibers, essential substances inside which are contained blood and lymph vessels. Formed by cells and by a dense network of fibers immersed in a dense hydrophilic gel, is a highly resistant fabric and is able to support and provide nourishment to the epidermis.
Fibroblasts are the main cells of the dermis and appear as elongated and flattened cells.
The main function of the collagen fibers is to support the entire skin structure allowing its extension.
The elastic fibers are produced by fibroblasts and consist of two distinct components : elastin and microfibrils tubes.
Fundamental substance of the dermis is not fibrous extracellular matrix .
The aging of the dermis
The dermis, with the passage of time, undergoes a remarkable change that affects both the number of cells and their content elastic, reduces the degree of cell turnover while old cells are replaced more slowly and the tissue becomes more consistent .
It follows that a decrease of hyaluronic acid cha has the ability to retain substantial amounts of water, keeping the skin young . The visible consequence of these degenerative processes is the formation of wrinkles, stretch marks and streaks of double chin, withering skin and loss of elasticity.
Wrinkles are the most obvious sign of atrophy of the skin and are distinguished:
Facial wrinkles linear
Facial wrinkles glifiche ( typical consequence of overexposure to sunlight or sunlamps)
Wrinkles or creases sleep
Puckering of the skin of the body of elders
Nasolabial folds

The constant commitment of Derma Medical Group is to ensure the highest quality of its prodotti.Gli ingredients used, capable of responding to new and growing expectations , are aimed at improving three fundamental aspects of the product : safety , quality and efficacy. Quality and safety require that the production of the line is carried out without the use of dyes, preservatives , perfumes , silicones and petrolatum . The products are also not tested on animals .
Medical why they are used and active ingredients , including excipients, derived from aesthetic medicine and not from cosmetics , to cold extraction , where all the bodies remain intact, with no dyes, preservatives , silicones, parabens and fragrances . Derma because it works on two levels, internal and external , and exogenous and endogenous trying to stimulate the skin and skin structure from within and not from outside, such as cosmetics . Group because they are part of a series of medical plastic surgeons and dermatologists who , with their experience and needs , give life to a line of dermo-cosmetic products suitable for skin care in all aspects of the dermo-cosmetics , including skin tests and scientific of each active both in vitro and on particular subjects aged leather .
