Aging is an inevitable process that the human body experiences. The skin, like any other organ, experiences the deleterious effects of time. But unlike others, these disorders are visible to anyone around us. Moreover, it may express the signs of the diseases of other organs by excreting their toxins.

Our appearance plays a major role in our social relations, the way we feel about ourselves, and in the way others picture us. Therefore, it is important to take good care of our skin to delay any signs of aging.

Skin Anatomy

In order to determine preventive measures, you should first understand the structure and the roles of your skin as well as the factors which harm it.

The largest organ you have is your skin and its main function is as a protective barrier against any environmental factors, from simple injuries or infections, to sun rays, or any harmful substances.

Beside this, it has a lot of specialized cells and structures which get information from the outside and send it to the brain to process and regulate the behavior of the entire body.

The skin is made up of 3 layers:

1. the epidermis, an outer thin layer containing various types of epithelial cells along with cells that produce the skin’s pigment (melanin), cells that play an important defensive role (Langerhans’ cells), and Merkel’s cells which are suposed to function as sensitive receptors.
2. the dermis, which is the thickest one, containing a network of elastin, collagen and reticular fibers surrounding blood vessels, nerves, muscles, sweat cells, and hair follicles with oil-producing and apocrine cells. At this level there are also nerve cells serving as sensitive receptors for temperature, touch and pain.
3. and finally is the subcutaneous tissue, composed mostly of fatty cells, which have a resistance role.
