This Is Why Sunscreen Will Actually INCREASE Your Risk Of Skin Cancer.
by Edward Morgan.
Contrary to popular belief, using sunscreen will increase your risk of melanoma. Sunscreen
ingredients inhibit inducible nitric oxide synthase (iNOS). Sunscreens prevent UV-induced
redness, which occurs in part through the action of nitric oxide (NO), synthesized in
the skin. But NO is an important immunoregulatory molecule, and it is crucial in the induction
of the cell-mediated tumor immune response.
According to an article in Melanoma Research:
�These findings suggest that sunscreens may prevent redness partly by UV absorption
and partly by inhibition of the skin�s inflammatory response. As such, sunscreens might promote
instead of protect against melanoma.� Nitric oxide also acts to help lower your
blood pressure � another reasons to avoid sunscreens that destroy the chemical in your
body.
Researchers at the Environmental Working Group, a Washington-based nonprofit, released their
annual report claiming nearly half of the 500 most popular sunscreen products may actually
increase the speed at which malignant cells develop and spread skin cancer because they
contain vitamin A and its derivatives, retinol and retinyl palmitate.
Furthermore, the FDA has known about the dangers of vitamin A in sunscreens since ordering
a study 10 years ago, but has done nothing to alert the public of the dangers.
�Retinyl palmitate was selected by (FDA�s) Center for Food Safety and Applied Nutrition
for photo-toxicity and photocarcinogenicity testing based on the increasingly widespread
use of this compound in cosmetic retail products for use on sun-exposed skin,� said an October
2000 report by the National Toxicology Program.
According to AOL news, other problems with sunscreens include:
The use of the hormone-disrupting chemical oxybenzone, which penetrates the skin and
enters the bloodstream. Overstated claims about performance.
The lack of needed regulations and oversight by the Food and Drug Administration.
Also, be careful where you discuss the danger involved with sunscreens. Brazilian supermodel
Gisele Bundchen has reportedly �infuriated cancer experts� by describing sunscreen
as �poison�.
Bundchen refuses to use it on herself or her family because of the chemicals they contain.
According to the Daily Mail:
�[Bundchen] made the comments at the launch of her own organic skin care range, which
presumably doesn�t include sun care lotions.� Bundchen, incidentally, is currently the highest
paid supermodel in the world. She also has said that it should be against the law for
healthy mothers to give their baby infant formula full of sugar, and often soy.
Dr. Mercola�s Comments:
The FDA is once again on the wrong side of consumer safety, just as they have been time
and time again when they allow dangerous drugs onto the market that end up killing people
and are later recalled.
Failing to alert consumers of the dangers of vitamin A and its derivatives in sunscreens
falls in line with the FDA�s seemingly endless ability to protect their big business �clients�
at the expense of public safety. In this case the manufacturers of sunscreens are the beneficiaries
of the FDA�s inability or unwillingness to publish their own vitamin A safety research
that they conducted over 10 years ago in 2000.
For a long list of other FDA debacles through the years, just put �FDA� into my search
box at the very top of this, or any page at mercola.com.
Is Sunscreen Really a Necessity?
Let�s consider a question that naturally arises out of this latest failure by the FDA
� do you even need to use sunscreen in the first place?
The answer is �maybe�, and only when you can�t control how much sun you are exposed
to. For instance, if you work outdoors all day as part of your job, or if you need to
protect sensitive areas of your face, like around your eyes, that are particularly susceptible
to photoaging and not that large a surface area to impact vitamin D levels if blocked
with sunscreen.
But you certainly don�t want to use most of the commercially available sunscreens under
any condition as they not only block your body�s ability to produce vitamin D, they�re
also loaded with toxic chemicals. More about that in a minute.
However, sunscreens available in most health food stores, and the one we sell on our site,
are safe to use when the need arises.
The fact is, getting safe sun exposure every day is actually one of the best things you
can do for your health. Sun exposure allows your body to naturally produce your own supply
of vitamin D, and experts agree that this is the best form of vitamin D available.
The point to remember is that once your skin turns the lightest shade of pink (if you�re
Caucasian), it�s time to get out of the sun. Past this point of exposure your body
will not produce any more vitamin D and you�ll begin to have sun damage. And sunburn anywhere
on your body is never good for your health.
The Benefits of Vitamin D
First of all, vitamin D plays a crucial role in your overall health and well-being. If
you�ve spent any time on my site at all, you know that I�m a firm advocate for optimizing
your vitamin D levels.
For example, this superb nutrient is known to:
Support your cardiovascular health Support healthy kidney function
Enhance your muscle strength Promote healthy teeth
Help produce optimal blood pressure levels Help keep your bones strong and healthy
Help maintain a healthy immune system Please understand � this list of important
benefits represents a fraction of the many ways vitamin D helps optimize your health.
And, although you can obtain vitamin D from natural food sources, experts agree on one
thing:
Sunlight is by far the best way to get your vitamin D. The so-called experts who advise
you to avoid all sunlight and religiously apply sunscreen are actually encouraging you
to increase your risk of cancer, not lower it�
The key is to find a healthy balance between getting enough natural sunlight to maximize
your vitamin D production and maintain your optimal health, while at the same time protecting
yourself from damage that occurs from overexposure to the sun.
Sun Exposure Can Protect You Against Cancer
Over the years, several studies have already confirmed that appropriate sun exposure actually
helps prevent skin cancer. In fact, melanoma occurrence has been found to decrease with
greater sun exposure, and can be increased by sunscreens.
One such study revealed that melanoma patients who had higher levels of sun exposure were
less likely to die than other melanoma patients, and patients who already had melanoma and
got a lot of sun exposure were prone to a less aggressive tumor type.
Another Italian study, published in the European Journal of Cancer in June 2008, also confirms
and supports earlier studies showing improved survival rates in melanoma patients who were
exposed to sunlight more frequently in the time before their melanoma was diagnosed.
Also, Melanoma is actually more common in indoor workers than in outdoor workers, and
is more common on regions of your body that are not exposed to the sun at all. Additionally,
UVB radiation has been found to delay the appearance of melanoma if you are genetically
predisposed or prone to skin cancer.
To Prevent Skin Damage You Have to Protect Against the Most Damaging Rays
Ultraviolet light from the sun comes in two main wavelengths � UVA and UVB. It�s important
for you to understand the difference between them, and your risk factors from each.
Consider UVB the �good form� that helps your skin produce vitamin D.
UVA is considered the �bad form� because it penetrates your skin more deeply and causes
more free radical damage. Not only that, but UVA rays are quite constant during ALL hours
of daylight, throughout the entire year � unlike UVB, which are low in morning and evening,
and high at midday.
If you�ve ever gotten a scorching sunburn on a cloudy day, you now understand why; it�s
from the deeply penetrating UVA!
Since UVA�s are inherently more damaging AND persistently high during all daylight
hours, wearing a sunscreen that doesn�t protect you from UVA is going to give you
virtually no benefit, and be detrimental to your overall health. So the first thing to
understand about using sunscreen, when applicable, is to make certain you are actually getting
UVA protection.
A Better Alternative to Sunscreen
One of the best strategies to protect yourself from the sun is actually not a sunscreen at
all, it�s wearing clothing or getting into the shade.
Why?
Because most sunscreens are loaded with toxic chemicals that can actually accelerate skin
cancer, or get into your bloodstream where they can disrupt your hormones. Also, the
protection sunscreen manufacturers claim is often misleading due to improper application.
So you don�t always need to apply sunscreen, and you definitely do want to get some safe
sunlight exposure every day, which has also been shown to help protect against as many
as 16 different types of cancer, including; breast, colon, endometrial, esophageal, ovarian,
bladder, gallbladder, gastric, pancreatic, prostate, rectal, and renal cancers, as well
as non-Hodgkin�s lymphoma.
Cotton clothing provides about SPF 15, in other words, you will get about 15-times your
skin�s normal protection from the sun wherever you cover your body with clothing. Just remember
that even with protective clothing on your body, it�s still important to monitor your
skin for the telltale signs of burning.
Remember, sunburn provides no benefit, and is never good for your skin.
So is Gisele Bundchen Right?
Until very recently all sunscreens did NOT filter out the UVA radiation. They filtered
out UVB, ensuring that your body could not make any vitamin D, while letting the UVA
through. So there was a strong recommendation from the medical community to use sunscreen,
but this advice was actually increasing your risk of cancer while eliminating your body�s
ability to manufacture vitamin D!
The other issue is what type of chemicals does the sunscreen use to create the barrier
against the UVA waves?
The synthetic chemicals often used in sunscreen preparations can get into your bloodstream
and can cause all sorts of unwanted toxic side effects, including hormone disruption.
Some of these chemicals include:
OMC (Octyl methoxycinnamate) Octocrylene
Avobenzone Oxybenzone
Homosalate Octinoxatre
Octisalate
So if Gisele was referring to sunscreens containing these hormone-disrupting synthetic chemicals
that do not even protect against UVA rays, then she was absolutely right!
Safer Sunscreen Alternatives
However, options do exist to provide safe protection from the sun during times when
you may not be able to control the amount of sun exposure you are likely to receive.
For instance, if you take your kids to an amusement park or the beach, you might just
be in direct sunlight all day.
To get natural sun protection from both UVA and UVB rays, you will want to use a sunscreen
product that contains the active ingredients of titanium dioxide and zinc oxide. My research
team has put together what we think is superior sun protection and you can find more about
it here.
You want to be cautious not to include any vitamin A in your sunscreen, or its derivatives
retinol and retinyl palmitate.
Other safe ingredients that will nourish your skin include:
Coconut oil Jojoba oil
Sunflower oil Shea butter
Vitamins D and E Eucalyptus oil
Vitamin A�A Dangerous Sunscreen Additive
The sunscreen industry uses vitamin A in its formulations because it is an anti-oxidant
that is thought to slow skin aging. But according to the AOL story cited above, the FDA�s
study of vitamin A�s photocarcinogenic properties revealed that:
�tumors and lesions developed up to 21 percent faster in lab animals coated in a vitamin
A-laced cream than animals treated with a vitamin-free cream.�
This conclusion came from Environmental Working Group�s analysis of the findings released
the FDA and the National Toxicology Program.
Why hasn�t the FDA released these findings and alerted the public to the possible dangers
of using a sunscreen that includes vitamin A or its derivatives?
No one is really certain why the FDA again refuses to listen to its scientists and doctors.
But this type of behavior has become standard operating procedure for the FDA, an agency
that routinely protects the business interests of corporations instead of following their
stated mandate to protect the public health.
Our sunscreen used to have vitamin A in it until I discovered its potential health problems.
We immediately removed it, however many other brands still include it in their formulas,
so beware, and always check the labels when shopping for sunscreen.
How to Research Your Sunscreen
Thanks to the Environmental Working Group, you are now able to see exactly how your sunscreen
rates for safe ingredients and efficacy. Check out EWG�s Sunscreen Guide here.
Their website also lists the titanium and zinc containing sunscreens receiving the highest
ratings, as well as provides you with some non-mineral options that rank lowest on the
toxicity scale.
The site is also a great reference for surprising facts about sunscreen, and also contains a
sunscreen hall of shame, showing the absolute worst offenders on the toxicity scale. And
lastly, according to their website, 1 in 8 sunscreens sold on the market today stilloffer
no protection against UVA rays!
Astaxanthin as the Hottest New Internal Sunscreen
Yes, a specific nutrient has been identified as being profoundly useful in protecting against
sun damage!
Astaxanthin has recently jumped to the front of the line in terms of its status as a �supernutrient,�
becoming the focus of a large and growing number of peer-reviewed scientific studies.
It�s produced from marine algae in response to exposure to UV light. This is the way the
algae protects itself, so it makes perfect sense that this deeply pigmented substance
would have the capacity to �shield� you when it is taken in large enough quantities
for a long enough time to saturate your body�s tissues. Typically this is several weeks.
One of the benefits of astaxanthin that has piqued the interest of researchers is its
ability to reduce signs of aging, by helping protect your skin from sun damage.
Cyanotech Corporation funded a study through an independent consumer research laboratory
to measure the skin�s resistance to both UVA and UVB light, before and after astaxanthin
supplementation. After taking 4mg per day for two weeks, subjects showed a significant
increase in the amount of time necessary for UV radiation to redden their skin.
Animal studies lend further evidence to astaxanthin�s effects as an internal sunscreen. Consider
the following:
In 1995, hairless mice were fed various combinations of astaxanthin, beta-carotene and retinol
for four months. After irradiation, astaxanthin alone or in combination with retinol was substantially
effective in preventing photoaging of the skin (as measured by markers for skin damage).
In a 1998 study with rats, astaxanthin was found to be 100 times stronger than beta-carotene
and 1000 times stronger than lutein in preventing UVA light-induced oxidative stress.
The Journal of Dermatological Science published a study in 2002 finding astaxanthin is able
to protect against alterations in human DNA induced by UVA light exposure.
Some Other Tips to Decrease Your Risk of a Burn
Controlling your exposure to the sun is not always possible, and sometimes even the most
vigilant of us forget to bring along the proper natural sunscreen when we face overexposure.
So what�s the best way to ensure your body is primed to have the best defense against
overexposure to the sun�s harmful UVA rays?
Consuming a healthy diet full of natural antioxidants has always been a useful strategy in not only
staying healthy but also providing your body with the resources to counter damage from
exposure to ultraviolet radiation. Fresh, raw, unprocessed foods deliver the nutrients
that your body needs to maintain a healthy balance of omega 6 and omega 3 oils in your
skin, which is your first line of defense against sunburn.
If you are regularly consuming processed foods and your cells are loaded up mostly with damaged,
oxidized fats, you simply aren�t giving your skin the proper fat protection it needs
at a cellular level.
Fresh, raw vegetables also provide your body with an abundance of powerful anti-oxidants
that will help you fight the free radicals caused by sun damage that can lead to burns
and cancer.
You can also make sure to wear a cap with a visor to protect your face and eyes from
direct sunlight, along with enough clothing to protect your skin from direct sun contact.
Most cotton clothing will provide you with about 15 SPF.
Also, I avoid using sunglasses, because I believe your eyes need to receive the full
spectrum of light to function optimally, and sunglasses block out some essential waves
of the light spectrum. So as you�re getting your healthy and necessary daily exposure
to direct sunlight to optimize your vitamin D levels, you want to be sure to leave
the sunglasses behind.
