Skin always regenerates itself by shedding the dead cells and generating new cells. This skin property keeps the skin looking nice and young. Skin is the largest organ of the body. It constantly keeps changing for becoming better or worse. Skin is made up of different proteins, lipids, chemicals and water. The most important job of the skin is to protect the body from infections and germs. The skin regenerates itself every 27 days.
There are different medical terms for the different layer of skin. Let’s have a look at those layers and their importance:
Stratum corneum: Outer most layer of dead skin cells.
Stratum corneum is the outer most layer of the dead skin that persists on the epidermis. A gentle regular scrubbing will remove or thin away this layer revealing the healthier skin beneath.
Epidermis: Outer layer of the skin.
The epidermis is the thinnest layer of the skin, but still this is layer which is solely responsible to protect the skin from the environmental hazards and its related effects. Epidermis has 4 layers of its own:
- Stratum germinativum
- Stratum spinosum
- Stratum granulosum
- Stratum lucidum
Epidermis also hosts various cells like keratinocytes, melanocytes and langerhans cells. Keratinocytes are responsible for producing the protein known as keratin, the main component of the epidermis. Melanocytes produce your skin pigment, known as melanin. Langerhans cells prevent foreign substances from getting into your skin.
Dermis: The middle layer of the skin.
This layer is where really the wrinkling takes place. This is the layer which is responsible for wrinkles. The dermis is a complex combination of blood vessels, hair follicles and oil (sebaceous) glands. This is the layer where you find collagen and elastin the two most talked about necessary proteins for your skin’s health as they offer firmness and elasticity. Fibroblasts are also the cells that you will find at this layer of the skin. Dermis is the layer that contains nerves that sense pain, touch and temperature.
Subcutis: The skin’s fatty layer.
Thinning or tissue reduction; at subcutis or at this skin’s fatty layer are responsible for causing wrinkles. This layer is comprised of sweat glands, fat and collagen cells. The subcutis is the layer that conserves your body’s heat and protects your organs from the outside harms of variation in temperatures.
Collagen and your skin.
Collagen is one protein that is found in abundance in the dermis layer. It forms up to 75% of the total organ. Collagen is one protein that keeps the wrinkles at bay. This collagen helps to maintain the youthfulness of your skin. With the age and the environmental factors make the collagen production lesser, resulting in fine lines and wrinkles.
Elastin and your skin.
Elastin resembles elastic. Yes whenever you think of this word elastin think elasticity. The protein is again found at the dermis layer and is responsible to give intactness and firmness with that springy bounce to your skin. With age even the levels and production of elastin gets affected causing sagging and hanging skin.
Keratin and your skin.
Keratin is one of the toughest and strongest proteins in your skin it gives rigidity to your skin. Keratin is also found in your nails and hair. It is one of the important proteins in terms of the health of your skin and hair.
