"Smart Aging Series - Part 1: Skin Health"
Dr. Stephen Sinatra, M.D.
June 2002
 The health of the skin is of special interest to me because my mother had skin
cancer, and I've had a pre-cancerous lesion removed from my back. Overall, skin
cancer is increasing at an alarming rate, and researchers predict that cases
will probably double in the next ten years.
I'm sure you've heard these frightening statistics before, but my point is that
they continue to show we're doing nothing about the issue. Most people attribute
the increase in skin cancer to environmental factors like the thinning of the
ozone layer. That's part of the problem, but human nature plays a significant
role, too. While we may not be able to control the ozone layer, it's certainly
possible to adjust our own health habits.
SUNBATHING: YOUR TICKET TO WRINKLES, CANCER
So many people feel they look healthier with "a little" sun. According to a
recent survey by the American Academy of Dermatology, 81 percent of respondents
thought they looked their best after having been out in the sun. but I've got to
tell you, if you've been out in the sun long enough for your skin to change
color - tan or pink - you've been out too long. Sun exposure is yet another
topic in which a little is good (we all need regular sun exposure of very short
duration, about 15 minutes a day on average, to help protect against
osteoporosis and maintain mood), but more is definitely detrimental.
Persuasive evidence shows that all three types of skin cancer - basal cell
carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma - are cause by sun
exposure. People who are really playing with fire include those:
- With repeated occupational sun exposure, like construction workers, farmers,
landscapers.
- With frequent recreational exposures, who are at greatest risk for BCC and
melanoma.
- With a history of sunburn (yes, even one bad sunburn in childhood is enough)
or benign skin damage such as brown spots and hyperpigmentation.
- Who use tanning beds (tanning salons are "Little Houses of Horror" in my
estimation) or sunlamps (not to be confused with lamps that emit natural light).
Chronic damage from sunlight makes possible the skin aging process (known
medically as photoaging) and the creation of patches of rough, scaly skin that
can become actinic keratoses, the earliest beginnings of skin cancer. If these
patches do transform into skin cancer, it's of the squamous cell variety.
Squamous cell is a low-grade affliction, but left untreated, it can spread and
potentially invade deeper tissues.
THE ABCs of SUN DAMAGE
There are three types of ultraviolet rays - UVA, UVB, and UVC, listed in order
from weakest to strongest. Despite its thinning, the ozone layer is still
absorbing all the UVC in sunlight, according to the National Aeronautics and
Space Administration. That's a good thing, because if it weren't we'd all be
dead.
UVB rays, the second strongest and most invasive of the sun's rays, are more
intense during summers months, especially at higher altitudes and in areas close
to the equator. These rays are the most common cause of the sunburns that result
in accelerated skin aging. Long-term exposure can cause skin cancers and other
immune system alterations.
UVA rays usually maintain a constant intensity throughout the year. They can
penetrate skin layers deeply, damaging collagen and elastin without your knowing
it, because there's no telltale sunburn. UVA also passes through glass and is
generated by fluorescent lights, so it's a problem even in the office. The
upshot: UVA is not safe for high-intensity exposure, no matter what tanning
salon operators may tell you.
SUN-SMART SUNBLOCK
Certainly avoiding prolonged direct exposures to UV light is the first step in
the right direction, and any sunblock or sunscreen is better than none at all.
But my recommendation is to buy the best protection you can afford. I've tried
dozens of products over the years and I've finally found one that meets my
standards. It's made by Dr. Jorge Suárez-Menéndez, a Miami-based plastic surgeon
who has used his expertise to create a maximum-protection sunblock. His
proprietary lotion contains a host of anti-oxidants, including extracts of
licorice root, red wine, seaweed, and green tea, in combination with proven
sun-shielding ingredients titanium dioxide and zinc oxide micro.
The MeSuá brand sunblock has been a real lifesaver for a high-risk person like
me. Though I am generally sun-avoidant, I won't give up my two favorite sports,
skiing and fishing, which subject me to large doses of sun. To order this
sunblock call 877-776-3782; for product information visit www.mesa.com. Because
the ingredients are pharmaceutical grade, this product is on the expensive side.
This cream is so potent, thought, that a thin film will protect you. And Dr.
Suárez-Menéndez is offering SHR subscribers 15 percent off their first purchase.
An off-the-shelf brand I like is Banana Boat's SPF 50 sunblock. But after I
discovered Dr. Suárez-Menéndez's product, I stopped using other brands.
By the way, when you're engaging in water or snow sports, always make sure that
your lips and nostrils are protected. Many people forget about their lips, and
the reflected ultraviolet rays can shine right into your nose.
EAT AND SUPPLEMENT YOUR WAY TO GOOD LOOKS
A diet that includes few sugars is crucial to your skin's health, as I wrote
last year in "Conversations Between the Heart and Skin" (SHR June 2001). High
polyunsaturated fat intake has also been associated with an increase in the risk
of skin cancer.
By contrast, the right fats in your diet can make all the difference. Regular
intake of omega-3s fatty acids in the form of fish oil, ground flaxseed,
walnuts, and avocados will help lubricate and protect the deeper, more
vulnerable tissues of your epidermis.
You also need sufficient amounts of Coenzyme Q10 because the skin uses this
nutrient at a high rate. When you're out in the sun, your skin's CoQ10 stores
can be depleted in as little as 15 minutes. So if you know you'll be outside all
day, fortify yourself with extra CoQ10.
Another tip: Along with plenty of water each day, make tea your beverage of
choice. Green or black, it's full of natural antioxidants known as catechins.
Research shows that if you add a twist of lemon, you'll reap the additional
benefits of d-limonene, an extract that appears to lower the risk of skin cancer
if used regularly.
Skin, the largest organ of the body, is vulnerable to oxidative stress, just
like the heart is. So make sure you take good care of your skin, the same way
you care for your heart.
