Understanding Our Skin

 

 

Your skin is your body's largest organ and it plays a vital role in maintaining your health and wellness. It's wonderfully resilient and can survive a great deal of punishment. The skin is the body's boundary layer, tough enough to resist all sorts of environmental assaults, yet sensitive enough to feel the slightest touch. The skin creates the first line of defense against possible invasion of bacteria and germs, while maintaining the body's internal environment within a few degrees of normal throughout our lifetime.

 

Self Care

When washing your face, use tepid (never hot) water and a washcloth or sponge to remove dead cells. Use a mild soap. You may need to clean oily skin two or three times a day. In general, avoid washing your body with very hot water or strong soaps - bathing can dry your skin. If you have dry skin, use soap only on your face, underarms, genital areas, hands and feet. After bathing, pat (rather than wipe) your skin dry, then immediately lubricate it with an oil or a cream.

 

Your Skin is Priceless

Match cosmetics to your skin type: An oil base is suitable for dry skin, and a water base is suitable for oily skin.

· For women, remove eye makeup before facial cleaning. Use cotton balls to avoid damaging the delicate tissue around your eyes.

· Shaving can be hard on a man's skin. If you shave with a blade razor, always use a sharp blade. Soften your beard by applying a warm washcloth for a few seconds; then use a Moisturizer. Moisture is critical to good skin health because it helps maintain a good skin barrier and creates a flexible, pliable skin that is soft to touch. Moist skin will tan better and more evenly.

 

Moisturize with Oil

A good moisturizer not only will add moisture to the skin, but also add some oils to the skin. People with severe dry skin require a moisturizer with more oils than a person with slightly dry skin.

 

Moisturize with Vitamins

A good moisturizer will help replace the vitamins skin needs. Vitamin E, or tocopheryl acitate, is a potent antioxidant that should be found in a good moisturizer. Vitamin C acts in concert with vitamin E in a healthy antioxidant system.

 

 

  

Vitamin D...the Sunshine Vitamin

 

            The benefits of vitamin D to skin, muscles and bones has been known for more than 50 years. But a growing body of research suggests it may also benefit heart health, reduce high blood pressure, help prevent certain forms of cancer, and curb depression and pain disorders.

 

 

The discovery by researchers that at least 30 percent of the U. S. population is vitamin D deficient has led to a burst of interest in the sunshine vitamin, which has long been known to help strengthen bones and boost the immune system.

"It was a total surprise," says Stavros C. Manolagas, chief of endocrinology and metabolism at the University of Arkansas for Medical Sciences.

"In retrospect, it turns out to be the way we dress, the way we eat, the way we avoid the sun based on the advice of our dermatologists ... all of that has caused an epidemic of vitamin D deficiency."

Manolagas said at least 30 percent to 40 percent of the population is vitamin D deficient. Others have estimated that as much as 70 percent of the population is deficient in the fat-soluble vitamin that allows the body to absorb calcium.

Doctors have known the benefits of vitamin D to skin, muscles and bones for more than 50 years. But a growing body of research suggests it may also benefit heart health, reduce high blood pressure, help prevent certain forms of cancer, and curb depression and pain disorders.

"This is probably the hottest topic in nutrition right now from a scientific research standpoint," says Todd Whitthorne, president and chief operating officer of Cooper Concepts, Inc., part of the Cooper Aerobics Clinic in Dallas. "Over the last three or four years, the research has just exploded."

But doctors also say much of the research remains inconclusive, and a lot is still unknown about vitamin D. As a result, there is an ongoing conflict between vitamin D experts who say a certain amount of sun exposure is essential to life, and skin-cancer experts who warn about the dangers of sun exposure.

"We're very concerned about reports that link the health benefits of vitamin D to unprotected ultraviolet exposure, because ultraviolet exposure is a known cause of skin cancer," says Andrew Kaufman, a dermatologic surgeon in Thousand Oaks, Calif., and a fellow of the American Society for Dermatologic Surgery.

As many as 90 percent of skin cancers are caused by sun exposure, with more than 1 million new cases expected to be diagnosed this year, he adds.

Vitamin D deficiency was called a "pandemic with a heavy public health burden," in a British Medical Journal article by Gregory Plotnikoff, medical director of the Institute for Health and Healing at Abbott-Northwestern Hospital in Minneapolis.

People who are vitamin D deficient are at increased risk for diabetes, hypertension, infectious and autoimmune diseases, and developing osteomalacia, or a softening of the bones, Plotnikoff wrote.

Harvard Medical School researchers say people who are vitamin D deficient are twice as likely to experience heart trouble, including a heart attack, heart failure or stroke within a five-year period compared with people with normal levels, in a Jan. 8, 2007 report published in Circulation: A Journal of the American Heart Association.

Other studies show that people who are vitamin D deficient are at an increased risk of certain types of cancer - including breast, ovarian, prostate and pancreatic cancer - Whitthorne says. An article this month in Cancer Epidemiology Biomarkers and Prevention notes that studies are inconclusive so far, but that maintaining sufficient levels of vitamin D might be a 'promising approach' to preventing or treating cancer.

Overall research linking vitamin D deficiency to different diseases is still under big debate, according to Manolagas.

The National Institutes of Health's Office of Dietary Supplements Web site says experts suggest five to 30 minutes of sun exposure between 10 a. m. and 3 p. m. at least twice a week to the face, arms, legs or back without sunscreen to maintain adequate vitamin D levels. But the federal agency also warns it is "important to routinely use sunscreen to help prevent skin cancer or other negative effects."

Daniel Davis, dermatopathologist at the UAMS, says he spends every day correcting the ravages of skin cancer, including removing people's noses, eyes and ears. While there is excitement over the possibility that vitamin D might help fight cancer, it's important to remember the known dangers of sun exposure, he says.

"Is the sun is important to human beings? Yes, we couldn't survive without it," Davis adds. "Does sun cause skin cancer? It's indisputable. So where is the happy medium?"

Kaufman said 1.35 million new cases of skin cancer were diagnosed in 2006, more than all other types of cancer. Sun damage builds up slowly over time, he said, so it could be as long as 20 years before a person develops skin cancer.

"Is it safe to get a little bit of color; is it safe to get tan? The answer is no," Kaufman says. "A tan, freckles or a sunburn are all signs of damage from the sun to a person's skin."

Manolagas recommends people use common sense.

"Certainly sunbathing for hours in the Caribbean is one extreme, and going outside with short sleeves in the summer for half an hour or one hour of work is a completely different thing," he says. "While people who are greater risk of developing skin cancer should take precautions, covering every part of your body and hiding from the sun is certainly not the way we humans were made."
