His 22-year-old surfing buddy came down with melanoma, and that is when Guerry knew he needed to find a better way to protect skin from the sun. 

Guerry (pronounced “Gary”) began researching sunscreen products and was appalled by what he found – all the available sunscreens pretty much sucked. In fact, it was worse than that: sunscreen products still are not doing what they say they do and are counterproductive – even causing some shocking health problems.

Except for one brand – a sunscreen Guerry developed through his knowledge and research. You see, Guerry is a lifetime member of the American Chemical Society. He is a chemical, mechanical, and materials science engineer and a chemist, possessing expertise related to chemical, mechanical, electrical, and medical products. 

He has combined this experience by assisting clients in pursuing intellectual property protection for over 25 years. He has direct experience in chemical processes, formulation chemistries, polymers and composites, service life prediction, and risk analysis, including risk reduction technologies. 

His passion involves developing of food-grade edible personal care products including sunscreen, food-grade edible alternatives to petroleum-based products like Vaseline® and Neosporin®, and antimicrobial/antibacterial chelated silver-zinc oxides which are both bioavailable and biocompatible.

He has directed and participated in audit and certification procedures regarding FDA, EPA, USDA, ISO-9000, ISO-14000/life cycle assessment compliance, and served as an expert witness in litigation proceedings, including medical devices. 

Guerry is a named inventor/co-inventor on over 100 US/PCT patents and pending patent applications.  

In this podcast, we cover: 

  • How sunscreens are affecting users endocrine system
  • What you should know about those SPF numbers like SPF 30, SPF 50, etc.
  • Why you should never put anything on your skin that you wouldn’t put in your mouth
  • What you should know about UVA and UVB radiation
  • The multiple problems that come after you start “tanning” via tanning beds or the sun
  • How UVC rays affect the body
  • Why Guerry’s sunscreen products are superior in the market

“Getting a tan” needs to stay in the 1990s.

Guerry explains why tanning is not a cool thing to do anymore: once your skin starts to tan, the skin is overexposed to UV radiation. This is something each of us should consider: do you want wrinkled, leathery skin when you reach your seventies or eighties? Our skin is our largest organ, and like any organ in your body, you want to take care of it. 

Did you know that people in Scandinavian countries look down on Americans’ obsession with tanning? A tan is not considered healthy in Scandinavia. The people of Asia view tanning the same way. In Japan, the geisha girls do not get tans. That “porcelain” looking skin is what most other countries want – not a tan.

Guerry explains that this does not mean you shouldn’t have any UV exposure to get Vitamin D. Some of these countries that shun the sun experience vitamin D shortages. So we must strike a balance between overexposure and no exposure. Guerry shares how much sun each day is optimal for health. 

If you live to age 65 in the U.S., your chances of getting some form of skin cancer are 50%.

This is why you need to listen to this episode: everyone is wearing sunscreen, but the rate of skin cancer is still outrageously high! Why? Many factors are contributing to this, and Guerry covers them all in his conversation with Wade. 

When you look at the data on sunscreen lotion sales and the incidence of skin cancer, they appear to correlate. Something is not right about our light exposure, sunscreen products, and skin cancer rates. Guerry has done the research and done the testing to provide sunscreen products that protect you from UV radiation and don’t cause other health problems. 

Guerry has a Ph.D. in chemical engineering. He is someone that knows what he’s talking about when it comes to the ingredients in your sunscreen, what those ingredients do to the body—both positively and negatively — and what combination of healthy ingredients you can put together to form effective, beneficial protections against the sun’s damaging rays. 

Stay tuned as Guerry flips the script on sunscreens. Get ready to have the best summer of your life!
