The skin is the largest organ of the human body. Your skin does far more than serves as a fancy covering to make you look good. In fact, the list of job responsibilities it handles is actually quite impressive. Dr. Goldfaden breaks down what your skin in actually doing all the time!

A bodyguard:

Your skin shields your insides from ultraviolet radiation and other forms of physical damage, it also carries a powerful defense system that seeks out and destroys any foreign invaders that manage to get through.

As a communicator:

Your skin is constantly sending you the latest news from the outside world. About 45 miles of nerves connected to heat and touch sensors located in your skin are always busy relaying vital information about your physical environment.

As a maintenance worker:

When the outside temperature gets too hot, your skin is in charge of regulating your interior thermostat. It automatically turns on the sprinkler system by activating close to 200 sweat glands per square inch. This helps cools you down because the perspiration evaporating on the skin surface lowers your body temperature. When the mercury dips too low, a tiny muscle at the base of every hair on your skin contracts and makes the hair stand up. This helps trap a layer of air on the surface that insulates you from the cold.

As a water conservationist:

On average, about 55% of a woman’s total body weight is water. This means that a 130 pound woman is made up of almost 36 quarts of water. What keeps all this moisture from evaporating and escaping into the air around you is your skin. The outer layer of your skin, although it’s thinner than a single coat of paint, is as water-tight as a plastic sheet of equal thickness. In fact, your skin is 1000 times more impermeable than the membrane of any other living organism.

As a waste management specialist:

Sweating does more than help regulate your body temperature. It actually takes out your garbage as well. Every day your body loses about two and a half quarts of water. A lot of this comes from your sweat glands that work overtime to rid your body of unwanted byproducts like urea and ammonia that are dissolved in your perspiration.

As a vitamin manufacturer:

Your skin houses all the necessary equipment to produce vitamin D from sunlight. Just 20-30 minutes of summer sun

can help generate 10,000 IU of vitamin D that your body needs to activate over 2000 genes responsible for controlling everything from bone growth to immune function.

Interesting qualities that make your skin truly unique:

• 12% to 15% of your total body weight is made up of skin
• By comparison, the second largest organ is the liver, weighing in at a little over 3 pounds
• Your skin sheds somewhere in the neighborhood of 40,000 cells every minute and replaces them with other cells that rise to the surface

How to keep your skin fully functioning:

Your cell turnover slows down every single day. Ever wonder why a baby’s skin is so soft? It’s because babies naturally replace their skin cells every few days. As you grow older, however, the rate of skin cell turnover slows down dramatically. Dead cells on your skin’s surface hang around much longer, a fact that tends to accentuate those fine lines and make your complexion look dull, gray and lifeless. By removing these dead skin cells, exfoliation helps make up for the gradual slowing down of your natural skin renewal process, improving the tone, texture and brightness of your skin.

The process of exfoliation is a lot like peeling away the dry, crinkly skin of an onion to reveal the living supple layers beneath. Whether the exfoliation is done using mechanical abrasion (Scrub) or a controlled chemical reaction (acid peels), removing dead and damaged skin cells on the surface allows the fresh new skin underneath to become visible. This newly exposed layer of skin feels much softer and smoother. Its surface reflects light better, making fine lines and other small imperfections harder to see. Age spots and other areas of unwanted pigmentation are less noticeable because the dead skin cells containing the pigment have been removed. Exfoliation unplugs clogged pores and allows for the release of natural skin oils. Regular exfoliation also helps to maintain open pores, decreases pore size, and minimizes many types of superficial scarring. In addition, removing the top layer of dead and damaged cells allows other health-promoting agents such as moisturizers, antioxidants, and collagen-boosting ingredients to better penetrate the skin and work more effectively!
