Structure of the Skin
"Skin Structure And The Effects Of Aging"
To better understand about the structure of the skin, first is interesting to know that the skin is the largest organ of the body and:- protects our internal organs
- help us resist bacteria and infection
- prevents excessive water loss
- gives shape to the body
- let our body breathe.
The structure of the skin is compose by three major skin layers:
The Epidermis
Is the thinner outer layer of the skin. Is made up of several layers called - Queratinocytes(Keratin)
- Melanocytes which produce
melanin
and determines the shade of our skin
- Langerhans which form part of the inmune system.
The Epidermis is composed by many nerve endings. New cells are constantly forming in the lower epidermis, and the oldest cells travel to the surface in a 30 day cycle where are worn off. Meanwhile, the new cells are ready beneath to replace the old ones.
So, what happens to the structure of the skin as we age?
The Epidermis becomes thinner, and the cells start to divide more slowly. Dead skin cells don't shed as quickly, causing the skin to look aged. There is a loss of melanin producing cells that protect us from UV radiation, and brown spots start to appear.
The second skin layer is
The Dermis.
Is the middle skin layer, and is the skin's main foundation. The dermis contains the proteins collagen and elastin, which give the skin support and elasticity.
It contains - blood vessels
- sweat glands
- nerves
- hair follicles
As we age the dermis becomes thinner and collagen and elastin, the skin's connective tissues, start to lose their elasticity. The skin's ability to retain moisture diminishes; becoming dryer.
The third layer of the skin is called
The Subcutaneus.
Is the deepest skin layer, is composed of fatty tissue and provides nourishment to the upper layers of the skin. Protects the body from heat, and cold and acts like a cushion to internal organs. It contains - nerve endings
- hair follicles
- sweat glands
- blood vessels that are lengthen to this layer from the dermis.
The depth varies from person to person, depending on how fat you are. The fat in the subcutaneus layer decreases as we get older, and the epidermis starts to sag, see
sagging skin
.
