Your skin does many things. It protects you from the sun's ultraviolet rays, it is a barrier that protects the body from the environment. These can include dirt, and bacteria, plus and types of environmental hazards that can threaten your health.

Another role the skin plays is that of an early warning system because of the nerves that are embedded in the skin. These nerves warn the body about hot, cold; sharp, dull; hard, soft experiences you can have everyday. It is one of the organs of sensation.

The skin regulates the moisture in the body, the temperature, and as one way the your body uses to remove waste products that build up in the process of just living.

And, the skin is considered to be your body's largest organ.

The skin is made up of 7 parts. The top layer of your skin is called Epidermis. This is the part you see. Below this layer is the thicker layer called the Dermis. This thick secondary layer is made up of strong and elastic tissue. Inside the Dermis you will find oil glands --they are called called Sebaceous glands. Also, your veins, arteries, and nerves are imbedded in the dermis.

The skin repairs and restores itself by creating enzymes that break down old collagen and making new collagen--hopefully at about the same rate. Collagen makes up about 80% of skin and is what makes the smooth or wrinkled depending on how this process is working for you.
