Take A Closer Look At The Skin Layers

The skin comprises of three main layers namely dermis, epidermis and subcutaneous tissues.  The health of the skin depends on each of these layers performing their functions to optimal levels and also support each of the other layers.

The Epidermis

This is the outer layer of the skin. It consists of three sub-layers known as outer stratum corneum, middle squamous cell layer and the bottom basal cell layer. The visible part of the epidermis is called stratum corneum. It is the layer of the dead skin cells.

This layer makes use of a protein called keratin. It forms a substantial barrier between the outside environmental factors and the vulnerable skin cells present in the body. Various cells make the epidermis, and they are:

  • Basal Cells: These are found at the bottom of the skin layers and helps to reproduce new forms of keratinocytes continuously.
  • Keratinocytes: These are also known as squamous cells which are present in the middle of the epidermis and responsible for producing keratin. This protein forms a protective layer. This protein also helps healthy nail and hair growth.
  • Melanocytes: This produce melanin which is a pigment that provides the color of the skin. People that have dark skin color contain melanocytes which produce more of melanin. Excess skin exposure to skin can also enhance melanin production, causing freckles or a suntan.
  • Langerhans Cells: These are a part of the body’s immunity system and helps to combat infection.

Dermis

The Dermis

This is found below the layers of the epidermis and is held together by a protein called collagen. The dermis is vitally responsible for keeping the epidermis healthy and growing as well as supports the structure which aids the body in many ways:

  • Nerve endings: They are capable of transmitting sensory input into the brain. This causes you to sense texture, pressure, heat, and pain.
  • Blood vessels: helps to deliver nutrients and oxygen to the epidermis. They also contribute to eliminating the debris.
  • Oil Glands: This keeps the skin moisturized and avoid the formation of hair follicles from becoming brittle.
  • Sweat glands: This plays the role to maintain the body temperature regulated.

The Subcutaneous Tissue

This is a layer of the collagen and fat cells. It is the bottom-most layer of the skin. It helps to hold the body heat within and absorbs the impact of any infection or any injuries that could take place on the skin.

The Subcutaneous Tissue

Bottom Line

Looking at this, one must understand the importance of skin nourishment and protection. With dermis, epidermis and subcutaneous tissues playing an active role to keep the skin healthy, you must maintain that.

And by maintaining it, you should try to keep your skin nourished and fit. Also, make sure you cut down some of your habits that reduces collagen levels.
