Houston Heat: Is Sunscreen Baking PFAS Youth?

By Franklin Everett Shaw

The Houston sun beats down relentlessly, a constant reminder of the need for sun protection. But what if the very product we rely on to shield us is secretly exposing us to harmful chemicals? The uncomfortable truth is that many popular sunscreens contain PFAS, or per- and polyfluoroalkyl substances, also known as “forever chemicals.” These chemicals don’t break down in the environment or our bodies, and their potential health effects are deeply concerning.

The question then becomes: are we trading sun damage for PFAS exposure, and what can Houstonians do to protect themselves?

PFAS are a group of man-made chemicals used in various industries since the 1940s. They’re found in everything from non-stick cookware to firefighting foam, and yes, even some sunscreens. Their appeal lies in their ability to repel water and oil, making them useful in products designed for outdoor use.

The problem? PFAS are linked to a range of health issues, including:

Increased cholesterol levels
Immune system disruption
Thyroid problems
Liver damage
Kidney and testicular cancer

While the research is ongoing, the potential risks are significant enough to warrant caution, especially for vulnerable populations like children and pregnant women.

So, how are PFAS getting into our sunscreen? It’s complicated. In some cases, PFAS may be intentionally added for their water-repellent properties. In others, contamination can occur during the manufacturing process. Regardless of the source, the presence of these chemicals in products we apply directly to our skin is alarming.

Now, let’s talk about Houston. We’re a city known for our outdoor lifestyle, from strolling through Hermann Park to enjoying a day at Galveston Beach. This means we rely heavily on sunscreen. But the combination of intense sun exposure and potential PFAS absorption from sunscreen could be a recipe for accelerated skin aging and other health problems.

Think about it: prolonged sun exposure already damages collagen and elastin, leading to wrinkles and age spots. If we’re simultaneously exposing our skin to PFAS, which some studies suggest can disrupt cellular function and contribute to oxidative stress, are we exacerbating the aging process? It’s a question that demands further investigation, but the preliminary evidence is unsettling.

Finding PFAS-free sunscreen in Houston requires a bit of detective work. Major retailers like Target, CVS, and Walgreens are starting to carry more natural and organic options, but it’s crucial to read labels carefully. Look for sunscreens that are mineral-based, using zinc oxide or titanium dioxide as the active ingredients. These ingredients are generally considered safer and less likely to contain PFAS.

Here are a few brands readily available in Houston that often offer PFAS-free options:

Badger Balm: Known for their simple, organic ingredients.
Thinkbaby/Thinksport: Specifically formulated for babies and athletes, with a focus on safety.
Raw Elements: Reef-safe and environmentally conscious.
Blue Lizard Australian Sunscreen: While some Blue Lizard products contain chemical filters, they also offer mineral-based options. Always check the label.

Don’t just rely on marketing claims. Look for certifications like the EWG (Environmental Working Group) Verified mark, which indicates that a product meets strict safety standards.

For the truly adventurous, consider making your own sunscreen. It’s a cost-effective way to control the ingredients and avoid potentially harmful chemicals. Here’s a simple DIY recipe for a Texas-friendly sunscreen:

Ingredients:

1/4 cup Zinc Oxide powder (non-nano)
1/4 cup Coconut Oil (provides some natural SPF)
2 tablespoons Shea Butter (moisturizing and soothing)
2 tablespoons Beeswax (helps with consistency and water resistance)
Optional: A few drops of essential oil for scent (lavender, chamomile, or carrot seed oil are good choices)

Instructions:

Melt the coconut oil, shea butter, and beeswax in a double boiler or a heat-safe bowl set over a pot of simmering water.
Once melted, remove from heat and let cool slightly.
Slowly add the zinc oxide powder, stirring constantly to ensure it’s evenly distributed. Avoid inhaling the powder.
Add essential oils, if desired.
Pour the mixture into a clean container and let it cool completely.

Important Considerations:

This recipe provides an estimated SPF of 20-30, but it’s difficult to determine the exact SPF without laboratory testing.
Reapply frequently, especially after swimming or sweating.
Store in a cool, dark place.
Always test a small amount on your skin before applying it to your entire body to check for any allergic reactions.

Making your own sunscreen can be tricky. A common mistake is not dispersing the zinc oxide properly, which can lead to uneven protection. Use a whisk or immersion blender to ensure the powder is fully incorporated. Another pitfall is using too much essential oil, which can irritate the skin. Start with a small amount and adjust to your preference.

Beyond sunscreen, there are other ways to minimize sun exposure and protect your skin. Seek shade during peak hours (10 am to 4 pm), wear protective clothing like hats and long sleeves, and consider using a UV-protective umbrella.

Living in Houston means embracing the outdoors, but it also means being mindful of the potential risks. By choosing PFAS-free sunscreens, practicing safe sun habits, and staying informed, we can protect our skin and our health while enjoying everything the Bayou City has to offer. The key is to be proactive and make informed choices. Don’t blindly trust labels; do your research and prioritize your well-being. Your skin will thank you for it.
