Are you using TOXIC sunscreen?

5 06 2010

Sunscreen blocks your body’s production of vitamin D, and most brands contain toxic free radical generators which I believe can increase your risk of disease!

The Sun is Not Deadly

In fact, the sun is healthy for you. Think about it. How could it be any other way?

After all, your ancestors survived outdoors, working outside under the sun’s rays far more often than they were indoors and out of the sun.

This brings up an obvious question.

How on earth would it be possible for your body to end up being configured in such a way that the sun is now a deadly threat to you, me, and the entire human race?

Like I said, it simply isn’t true.

That’s not to say sunlight can’t be harmful. Of course, it can be…

For instance, long-term, excessive exposure to sunlight can increase the risk of certain types of skin cancer. Yet moderate sun exposure is less dangerous than sporadic sun exposure.

Plus, there’s a good deal of evidence that sun exposure without sunburn significantly decreases the risk of melanoma (a more deadly form of skin cancer.) So safe sun exposure is key.

What You Should Know About UVA and UVB 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 guy’ — though of course you can’t de-select UVA if you’re going to be in the sun. UVB helps your skin produce vitamin D.

UVA is considered the ‘bad guy’ because it penetrates your skin more deeply and causes more free radical damage. Not only that, but UVA rays are quite constant during all the hours of daylight throughout the entire year.

By comparison, UVB waves are low in morning and evening and high at midday.

So, if you’re out early in the morning or late in the day, you get lots of UVA (bad guy) and not much UVB (good guy). Not a good way to produce vitamin D. Plus you increase your risk of cancer if that’s your only sun intake, and you fail to protect your skin.

What’s more, have you ever gotten a scorching sunburn on a cloudy day? You think you don’t need to protect yourself and you wind up being really sorry you didn’t. That’s the UVA rays at work. They can break through cloud cover and pollution and do some real damage your skin.

Wearing a sunscreen on your uncovered skin blocks your body’s production of vitamin D. In fact, sunscreens reduce vitamin D production by as much as 97.5 to 99.9%. And interfering with your body’s production of vitamin D by 97.5 to 99.9% may have dire health consequences.

After all, vitamin D plays a crucial role in your overall health and well-being. For example, this superb vitamin is known to:

-Support your cardiovascular health

-Promote optimal cholesterol levels

-Enhance your muscle strength

-Help produce optimal blood pressure levels

-Help maintain a healthy immune system

-Support healthy kidney function

-Promote healthy teeth

-Help keep your bones strong and healthy

Should You Use a Sunscreen to Guard Against SUNBURN?

Absolutely! But not any kind of commercial sunscreen.

As much as I prefer you steer clear of sunscreens because they interfere with natural vitamin D production, there is one critical exception. The exception is when it is impossible to limit full body exposure to sunlight! So if you can’t limit your exposure for whatever reason, do use a safe sunscreen to protect your skin from sunburn. It is for YOUR own good. Your risk of getting melanoma may increase in relationship to sunburn frequency and severity. Limiting sun exposure, wearing protective clothing, and using a 100% all-natural, non chemical sunscreen can reduce the risks of skin cancer and other harmful effects of the sun. Studies revealed that people who spend more time outdoors without getting sunburn, actually decrease their risk of developing melanoma.

Now get this:

Safe sunlight exposure has also been shown to protect against as many as sixteen 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.

So, yes, your body needs a bit of unprotected sun exposure. For all the benefits I’ve mentioned earlier. But if you can’t avoid the following three scenarios:

-You’re forced to be in the direct rays of the sun for a longer time than is safe…

-You must go into intense sunlight without having the opportunity to gradually build up to it…

-You’re in a situation where blocking the sun with strategic clothing or sunshades is impractical…

…use a sunscreen to help guard against sunburn. But, don’t just slap on any of the standard commercial brands you find on store shelves. With that in mind…

Clothing Can Protect You — Especially Caps

Additionally you can use clothing wisely to avoid sun induced skin damage. My favorite is a cap which allows me to avoid wearing sunglasses and benefit from all of the 1500 wavelengths in sunshine. But the cap also keeps the sun off the very thin skin around my eyes which is particularly sensitive to photoaging damage from the sun.

It’s Time to Expose the Sunscreen Smokescreen!

In my opinion, corporate greed has created products that are harmful. I’m talking hundreds of sunscreens that I believe are toxic because they contain man-made chemicals … chemicals I believe can cause serious health problems and increase your risk of disease. Here’s why.

The main chemical used in sunscreens to filter out ultraviolet B light is octyl methoxycinnamate. OMC for short. OMC was found to kill mouse cells even at low doses. Plus, it was also shown to be particularly toxic when exposed to sunshine. And guess what?

OMC is present in 90 percent of sunscreen brands! But that’s not the half of it. A common ultraviolet A filter, butyl methoxydibenzoylmethane, has also demonstrated toxic properties.

Furthermore, several studies show that the chemicals commonly used in sunscreens are absorbed through the skin and end up circulating in your blood stream. Not good. So…

Toss your sunscreen in the trash if it contains any of these questionable chemicals:

Para amino benzoic acid

Octyl salicyclate




Padimate O





Menthyl anthranilate

Trolamine salicyclate


Chemicals such as dioxybenzone and oxybenzone (two chemicals I just mentioned) are some of the most powerful free radical generators known to man!

So if your sunscreen contains dioxybenzone, oxybenzone, or any of the other chemicals I just revealed, I highly recommend you switch to a formula that is safe and healthy for your skin.
