Dr. Oz: Your Sunscreens Are Poisoning You With Cancer-Causing Chemicals


People have been using sunscreens when exposed to sunlight for almost 100 years.

The goal was to obstruct ultraviolet (UV) light, the harmful rays of the sun.

Sunscreens started with pasty zinc oxide that nobody would use.

So scientists created a sunscreen with clear chemicals that took in UV light.


In 1944, Coppertone ® ended up being the very first mass-marketed sunblock.

Fast forward to now, when about a billion dollars worth of sunscreen are offered each year in the United States.

Too much exposure to UV light can trigger skin cancer and prematurely age the skin.

Too little sunlight exposure can also have a negative impact on our health.

It’s extremely important to safeguard our skin and retain a safe balance when spending time in direct sunlight.

We do not want to block sunshine entirely– about 20 minutes each day is great for us– it enhances our vitamin D and improves our mood.

Beyond 20 minutes at a time, however, and our body immune system suffers.

We either have to spend the remainder of the day inside or secure our skin.

Sunscreens can poison you

There are 17 specific sunblock components that are FDA authorized: 15 of these are clear chemicals that soak up UV light and 2 are made of minerals that reflect UV light.

Of these 15, 9 are known endocrine disruptors.

To be efficient, chemical sun blocks have to be rubbed into their skin 20 minutes before sun exposure.

They do a respectable task at obstructing UV light.

However, they get used up as the sun shines on them.

In fact, some sunblocks lose as much as 90% of their effectiveness in simply an hour, so they require to be reapplied typically.

This is not the case with zinc oxide and titanium dioxide, the 2 mineral, or physical, sunblocks.

These two work extremely differently– they sit on the surface of the skin and physically block UV light.

Chemical sunblocks do not sit on the surface area of the skin– they soak into it and rapidly find their method into the bloodstream.

They scatter all over the body without being detoxified by the liver and can be detected in blood, urine, and breast milk for approximately two days after a single application.

That would be just fine if they were consistently safe– but they’re not.

9 of the 15 chemical sunblocks are thought about endocrine disruptors.

Those are chemicals that hinder the regular function of hormones.

The hormonal agents most commonly disturbed are estrogen, progesterone, testosterone, and thyroid.

Endocrine disruptors, like some active ingredients in chemical sunscreens, can cause the irregular development of fetuses and growing kids.

They trigger early the age of puberty and early breast development in girls, and little and undescended testicles in young boys.

They cause low sperm counts and infertility.

Chemicals in sunscreens cause cancer

Endocrine disruptors that imitate estrogen can contribute to the development of breast and ovarian cancers in women.

Other endocrine disruptors may increase the possibility of prostate cancer in men.

Sounds pretty unsettling, doesn’t it?

But there’s more.

Chemical sunscreens work by soaking up UV light.

At the same time, some may get utilized up and alter.

Some produce DNA-damaging chemicals called “free radicals.”

These might lead to cancers.

According to Professor Author W. Perry, the lead medical advisor on the Dr. Oz Show, when looking at the relationship between sunscreen and cancer, he says, “Where there’s smoke, there’s fire.”

Dr. Perry, who is one of leading plastic surgeons in the US and the Adjunct Associate Professor at Columbia University, explains why there’s so little data linking sunscreen to cancer:

“Poisoning that takes place over decades is difficult to study.

“Chemicals like arsenic and botulism make us sick very quickly, and so it was easy to figure out that they are toxins.

“Lead is a toxin that takes longer to cause illness,  so it was many years before the government listened to scientists and restricted its use.

“And chemical sunscreens are even harder to study since their effects are subtle and take a long time to appear.

“You might be saying, ‘Why is this guy – a plastic surgeon – saying something I’ve never heard about before?’

“This information isn’t new for me.

“My patients know I’ve been talking about sunscreen and other cosmetic toxicity for about 15 years.

“But I’m just an interpreter of science.

“And experts agree with me.”

Leading experts agree

R. Thomas Zoeller, MS, Ph.D., is a Professor of Biology at the University of Massachusetts.

He’s an author of the Endocrine Society’s clinical declaration about endocrine interrupting chemicals and their main agent.

Speaking in response to Dr. Perry’s conclusion on the dangers of sunscreen, he says:

“Dr. Perry makes an important point that sunscreens are applied to skin in a formulation that serves as a drug delivery system and that some sunscreens are known to interfere with hormone action.

“The way in which these chemicals can interact with hormone systems could plausibly increase the risk of various cancers as well as other endocrine disorders.”

What is the alternative?

If there were no good alternatives, we ‘d be in a pickle– we ‘d have to make some tough choices whether to use sunblock.

However, luckily, we have great options.

Zinc oxide and titanium dioxide are rocks that are ground down to a fine consistency.

They do a terrific task at obstructing both UVA and UVB light.

Zinc is less whitening on the skin and blocks nearly all unsafe UV light.

Inexpensive versions of these sunscreens are gooey and while you might put them on your kid’s skin, many people do not like them.

But more recent zinc oxide sunblocks contain particles so little that they are transparent.

These sunscreens are called micronized and do a great job at securing versus UV radiation.

Even newer sunblocks use rocks that are ground into smaller bits called nanoparticles.

Nanoparticles have their own issues, and some individuals do not consider them to be evenly safe.

There are also lots of natural alternatives to cancer-causing chemical sunscreens.

You can even make your own sunscreen using all natural ingredients such as:

  • Almond Oil
  • Coconut Oil
  • Zinc Oxide
  • Red Raspberry Seed Oil
  • Carrot Seed Oil
  • Shea Butter

I really do feel that people are poisoning themselves by putting ounce-quantities of chemical sunblocks on their bodies.

It’s hard not cringe when I see ladies, especially pregnant or breastfeeding women, and little children slathering that stuff on their skin.

Bottom line?

Use a micronized zinc oxide consisting of SPF 15 broad-spectrum sunblock every day of the year and an SPF 30 when you’re on the beach or out in the garden.

Or find natural alternatives that are not loaded with cancer-causing chemicals.

How much should you use?

An ounce spread over your whole body need to do it.

And reapply it every 2 hours approximately.
