Getting to Know Your Skin
July 22, 2008Your skin is the largest organ in your body. If you stretched it out, it would cover about 20 square feet. It weights about 15% of our total body weight. Just like your heart and lungs, it’s a living, breathing part of your body to perform specific tasks. While the obvious reason for skin is to make us look more appealing then a giant sac of organs, it has many functions. Your skin protects your inner workings from the sun’s rays and infection. It insulates your body from heat and cold, repairs itself, and is aware of potential danger through the senses your sense of touch. It is the breeding ground for your blood vessels, sweat glands, and hair follicles. Trust us, your skin does a lot.
Your skin is made up of three layers: The lowest layer of skin is a layer of fatty material known as the subcutaneous layer. On top of that rests the dermis, which contains your nerves, hair follicles (when blocked, are the primary causes of acne), sweat glands, blood vessels. Finally, on top of the dermis is the epidermis, which is the outside layer of your skin that you can touch and feel.
The Layers of human skin
Now, most people do not know that epidermis is made up of three layers too! The outer layer of the epidermis is actually made up of dead skin cells. We lose around 30,000 dead skin cells per minute! There is a middle layer, and finally, an inner layer where new skin cells are produced. Your body is always regenerating itself. That’s why we heal when we get cuts. As your skin cells age, they move their way to the top layer. They begin to die out on this journey. What they lose in functionality as a cell, they make up for in toughness. The trip from a new cell to a dead skin cell takes about 2-4 weeks.
