The Skin Cancer Foundation Busts Myths about Vitamin D and Sun Exposure


Vitamin D is often called the “sunlight” vitamin because the body produces it when the sun’s ultraviolet B (UVB) rays are absorbed through the skin. The vitamin is essential for strengthening bones and building a healthy immune system, but it is often used as an excuse to justify sun exposure and tanning. However, according to a recent statement from the Skin Cancer Foundation, the healthiest and most effective way to absorb vitamin D is by eating a balanced diet and taking vitamin supplements. The Foundation also stated that sun exposure actually weakens the immune system, countering one of the key benefits of vitamin D.

“The misconception that exposure to UVB radiation is the optimal source of vitamin D puts people at risk for potentially life-threatening skin cancer,” Dr. Perry Robins, President of the Skin Cancer Foundation, said in the statement. “Furthermore, in most cases the body stops producing Vitamin D after just a few minutes of sun exposure.”
 
The Skin Cancer Foundation article listed some myths and facts related to vitamin D, sun exposure and tanning:
 
Myth: UVB radiation is a good source of vitamin D.

Fact: We can produce only a limited amount of vitamin D from UVB radiation. For Caucasians, that limit is reached after just five to 10 minutes of midday sun exposure.1 After reaching the limit, further exposure will not increase the amount of vitamin D in the body. Rather, it has the opposite effect: the vitamin D stored in the body begins to break down, leading to lower vitamin D levels. 4

Myth: Sun exposure is the only source of vitamin D.

Fact: Vitamin D can be obtained from oily fish (like salmon, fresh tuna, trout and sardines) and cod liver oil, as well as from fortified orange juice and milk, yogurts, and some cereals. Supplements are readily available and inexpensive.

Myth: Tanning beds are a healthy option for boosting vitamin D levels.

Fact: The indoor tanning industry often makes the false claim that indoor tanning is helpful for vitamin D production. In reality, vitamin D is received through exposure to UVB rays; the bulbs used in tanning beds mainly emit UVA rays. Tanning beds are a known carcinogen. Just one indoor UV tanning session increases users’ chances of developing melanoma by 20 percent, and each additional session during the same year boosts the risk almost another two percent. 5

Valentine’s Day has passed, but it’s not too late to treat yourself!


Want to treat yourself and your skin? This month Greenville Dermatology is offering a great deal on peels! If you’ve never had a peel, here are some FAQ’s to help you understand the benefits.

What are the benefits of a chemical peel?
Chemical peels can be done on the face, neck or hands. They can be used to:
·         Reduce fine lines
·         Treat wrinkles caused by sun damage and aging
·         Improve the appearance of mild scars
·         Reduce age spots, freckles and dark patches (melasma) due to pregnancy or taking birth control pills
·         Improve the look and feel of skin

Who should get a chemical peel?
Anyone who has fine lines, wrinkles, scarring or sun damage and is interested in correcting the blemishes without surgery should consider a chemical peel. (Sagging skin or bulges cannot be improved with peels and typically require cosmetic surgery.)

Is the peel painful?
During a chemical peel, most people feel a burning sensation that lasts about 5-10 minutes, followed by a stinging sensation. Putting cool compresses on the skin may ease the stinging. You may need mild pain medication during or after a deeper peel.

What types of peels does Greenville Dermatology use?         
We provide alpha-hydroxy glycolic acid, beta-hydroxy salicylic acid peels, and TCA (trichloroaecetic acid) peels. These chemicals loosen blackheads and decrease acne by removing the top layer of skin, revealing the resulting new, healthier layer of skin.
How long does it take for my skin to heal and to see results?
The amount of time for skin to heal varies by patient but could take up to 14 days. However, once your skin has healed, you will see immediate improvements. For optimal results, we recommend patients have a second peel within the next six months to a year.
If you want to improve the skin you’re in without surgery, a chemical peel may be just right for you! For more information or additional questions, please call us today at 864-242-5872.

Protect your eyes


 
When protecting yourself from sunburn, you most likely give the most attention to your skin. However, it is important that you protect your entire body from harmful UV rays, including your eyes. According to a survey from the American Optometric Association (AOA), nearly 35 percent of Americans admitted that they often forget to protect their eyes from the sun.

Sunburned eyes can cause both short-term and long-term effects. Symptoms include redness or irritation, tearing, pain, a gritty feeling (almost like there's sand in your eyes), blurry vision and temporary loss of vision (called photokeratitis or snow blindness). Long-term effects can include cataracts, benign growths on the eye, skin cancer of the eyelids and surrounding tissue, and possibly macular degeneration.

Recently, CNN newsman Anderson Cooper revealed that he went blind for 36 hours after the sun’s reflection off of the ocean sunburned his eyes. During a broadcast of his daytime talk show Anderson Live,  Cooper explained, “I woke up in the middle of the night and it feels like my eyes are on fire…I think, oh maybe I have sand in my eyes or something…It turns out I have sunburned my eyeballs...I went blind for 36 hours.”

According to the AOA, eye damage due to UV rays is cumulative, so it is never too late to start protecting your eyes. Following are some tips for getting started:

1.       Wear protective eyewear any time your eyes are exposed to UV light, even on cloudy days and during winter months.

2.       Look for quality sunglasses that offer good protection. Sunglasses should block out 99 to 100 percent of both UV-A and UB-B radiation and screen out 75 to 90 percent of visible light.

3.       Check to make sure your sunglass lenses are perfectly matched in color and free of distortion and imperfection.

4.       Purchase gray-colored lenses. They reduce light intensity without altering the color of objects, providing the most natural color vision.

5.       Don’t forget protection for children and teenagers. They typically spend more time in the sun than adults.

6.       Schedule comprehensive eye exams.

These simple safety precautions can determine the fate of your eye health now and later in life. Isn’t your vision worth it?

Skin Cancer Foundation Filed Complaint Against Jersey Shore

Last week the Skin Cancer Foundation filed a formal complaint with the Federal Trade Commission (F.T.C), urging them to look into the promotional initiatives of MTV’s Jersey Shore’s. The Foundation is asking that the F.T.C. hold the show accountable for the excessive use and glamorization of tanning it believes is encouraging dangerous behavior among young viewers.
This formal complaint is not the Skin Cancer Foundation’s first attempt to initiate change. In 2010, the Foundation staged an intervention on the television show Extra; on air the cast pledged to change their behavior. However, we’ve seen in the past years that the cast members have continued to tan and talk about tanning. According to the Foundation, the topic is no longer part of organic conversation, but a recurring promotion of tanning.
With the latest filing, The Skin Cancer Foundation is demanding that MTV include with the show and all associated promotions a warning about the risks of skin cancer. The Foundation vehemently believes that if the Jersey Shore producers insist on endorsing excessive tanning, then the least they can do is disclose the related health risks to its impressionable viewers.
In an effort to prove its point, the Foundation assessed and identified an alarming 186 visual or verbal references to tanning in just 17 episodes. In one episode, cast member Paul DelVecchio (Pauly D) enthusiastically nominated himself “Most Likely to Get Skin Cancer.”
The Skin Cancer Foundation recognizes that it is not MTV’s responsibility to advocate or discourage tanning. However, MTV’s demographic is a core part of the population at higher risk for skin cancer. According to a report from the American Cancer society, the incidence of melanoma increased 800 percent in young women and 400 percent among young men from 1970 to 2009.
Do you think that MTV should be responsible for warning Jersey Shore viewers about dangers of tanning? Or do you think that it is a parent’s and individual’s responsibility to be educated on the risks of any behaviors or habits that they endorse?

UV Nail Lamps: Are they safe?



Gel nails and gel nail polishes have become a growing trend among American women. Similar to acrylic nails, gel nails are made from a monomer liquid that is combined with a polymer powder. This formula creates long polymer strands and once dried, those strands create a hard resin on top of the natural nail. Gel nails also contain shorter strands, called oligomers, which make the nail more flexible.

In order for the gel to harden, nails must be placed under a UV lamp, exposing the surrounding skin to UV light. As a result, many have asked if this exposure might lead to skin cancer. Some dermatologists have gone as far as claiming that these nail lamps are as damaging to the skin as tanning beds. However, according to an article published by WebMD Health News, the development of skin cancer as a result of exposure from a nail lamp is highly unlikely.

According to Dr. Alina Markova of Massachusetts General Hospital, “Nail lamps are safe for over 250 years of weekly manicures, and even then there would be a low risk of skin cancer.” Dr. Markova goes on to say that the lamps are not completely risk free, but that they pose little risk.

In a different article, dermatologist and clinical researcher, Dr. Susan Taylor shared her concerns relating to gel nails -- one being exposure to UV light. She also mentioned the exposure to a chemical ingredient call methyl acrylate, which has been known to cause a rash when it comes in contact with the skin, and also that constant application and removal of gel polish will lead to weaker and flaking nails over time. Her suggestion to counter these potential problems is to moisturize your nails several times a day.
Dr. Markova has been one of the only researchers to conduct a credible study on the effects of the UV lamp. So without further information, it is difficult to determine the safety of gel manicures. As a dermatologist, I never promote the use of artificial UV lamps if not 100% necessary. So the question you would need to ask yourself is whether or not even a minimal risk is worth a long lasting manicure.

Put down the fruitcake!

As you know, fruit cake and other holiday desserts are loaded with sugar. Did you also know that sugar makes your skin dry and dull and leads to wrinkles?

The cause is a process called glycation, in which the sugar in your bloodstream attaches to proteins to form molecules called advanced glycation end products (AGEs). Unfortunately, the collagen and elastin proteins that help keep our skin firm are most vulnerable to glycation. Once damaged, collagen and elastin fibers become brittle, causing wrinkles to form and skin to sag. According to an article in the British Journal of Dermatology, these negative effects can begin to appear around the age of 35 and rapidly increase after that.

Luckily, new collagen can be built with products that contain retinoids; ask your doctor about lotions and serums that have retinol. Once you have used a collagen building product, it is important to take further steps to keep your skin looking healthy and young.

First and foremost, reduce your sugar intake and apply a broad spectrum sunscreen daily. Next, be sure to drink plenty of water, and consider supplementing your diet with at least 1mg of B1 and B6 vitamins every day.

Green tea is also a great antioxidant. When used topically, it can more easily reach the dermal layer of skin where collagen and elastin reside.

Greenville Dermatology will be closed on Christmas Eve and Christmas Day, but we are happy to share with you a recipe for a green tea face mask that you can mix at home:

·         Brew green tea; double the usual amount of tea, but keep the amount of water the same. You want the tea to be potent.

·         Let the tea cool to room temperature.

·         Add 3 to 4 tablespoons of rice flour; you want a smooth consistency so that it is spreadable, but not runny.

·         (Optional) Add half of a mashed banana and/or mango; banana moisturizes and mango cleanses.

We encourage using prescription lotions and serums for more drastic results, but this mask is a great home remedy to tone skin between treatments.

So, apply your mask, grab a bottle of water and ring in 2013 with great skin!

Does the cost justify the means?



According to a recent article in Medpage Today, an estimated 75,000 cases of melanoma are expected to be reported in the United States in 2012. Considering that melanoma has been tagged as the deadliest form of cancer, it should be no surprise that there is ongoing research to find a cure.

In 2011, a BRAF inhibitor called vemurafenib (marketed as zelboraf), was approved by the FDA after exhibiting significant increases in the survival rates of patients in the late stages of melanoma. Prior to zelboraf, dacarbazine was the only treatment available to those diagnosed with melanoma. However, the medication proved to be effective in only 7-12 percent of all cases. In addition to increasing a patient’s chance for survival, zelboraf has also been shown to improve a patient’s quality of life and self-sufficiency.

Unfortunately, while the statistics relating to zelboraf are promising, the cost for treatment is extremely discouraging. Angie King, a PharmD student at Northeastern University in Boston, has been conducting a budget impact study to determine if the cost of zelboraf justifies its use in Medicaid programs. 

According to King, conventional treatment with dacarbazine would cost $31,873 per year, whereas a year of treatment with the traditional drug plus vemurafenib could cost as much as $314,347. That is a startling difference, but refusing to offer this new treatment due to cost could raise major ethical questions.

Do you think that an expensive drug such as zelboraf should be made available through Medicaid if it saves lives?
