When you grab a bottle of sunscreen, your main goal is to protect your skin from the sun’s harmful rays. But did you know that some sunscreens might be hiding harmful chemicals known as PFAS (per- and polyfluoroalkyl substances)? PFAS in sunscreen is a growing concern because these “forever chemicals” have been linked to serious health risks. If you’re mindful about what you’re putting on your skin, here’s what you need to know about PFAS in sunscreen and how to avoid them.
What Are PFAS, and Why Should You Care?
PFAS are synthetic chemicals that don’t break down easily, either in the environment or in our bodies. That’s why they’re often referred to as “forever chemicals.” They’ve been used in a wide range of products, from non-stick cookware to water-resistant clothing, and unfortunately, they’ve also found their way into some sunscreens.
So why does this matter? PFAS are linked to several health issues, including:
- Cancer: Certain PFAS are associated with an increased risk of kidney and testicular cancer.
- Hormonal Disruption: PFAS can interfere with hormone function, which may lead to reproductive issues and developmental problems in children.
- Immune System Effects: Exposure to PFAS can weaken the immune system, making it harder for your body to fight off diseases.
- Environmental Concerns: PFAS don’t just stick around in your body—they also persist in the environment, contaminating water supplies and harming wildlife.
Why are PFAS in Sunscreen?
PFAS can end up in sunscreen in two main ways:
- Intentional Use: Some manufacturers add PFAS to sunscreens to make them water-resistant or to create a smoother texture. While this might make the product more appealing, it also increases the health risks.
- Contamination: PFAS can also end up in sunscreen through contamination during manufacturing. This can happen when the raw materials or equipment used are tainted with PFAS.
The Risks of Using Sunscreens Containing PFAS
When you apply sunscreen containing PFAS, these chemicals can be absorbed through your skin and enter your bloodstream. Since PFAS don’t break down easily, they can build up in your body over time. Studies show that nearly everyone in the U.S. has some level of PFAS in their blood. While it’s nearly impossible to avoid PFAS completely, using products like sunscreen that contain these chemicals only adds to your exposure.
How to Choose a PFAS-Free Sunscreen
The good news is that not all sunscreens contain PFAS, and with a little effort, you can find safer options. Here’s how:
- Read Labels Carefully: PFAS might not be listed by name, but look for ingredients like “PTFE” (polytetrafluoroethylene) or anything with “perfluoro” or “polyfluoro” in it. These are red flags.
- Research Brands: Some companies are committed to avoiding harmful chemicals like PFAS. Look for brands that are transparent about their ingredients and manufacturing processes.
- Use Resources Like the EWG: The Environmental Working Group (EWG) offers a guide to sunscreens, making it easier to find PFAS-free options.
- Opt for Mineral Sunscreens: Mineral-based sunscreens with zinc oxide or titanium dioxide as active ingredients are less likely to contain PFAS and are effective at providing broad-spectrum protection.
- Be Cautious of “Waterproof” Claims: Sunscreens labeled as water-resistant are more likely to contain PFAS. Instead, choose non-waterproof options and reapply more often.
Steps to Reduce Your PFAS Exposure
In addition to choosing a PFAS-free sunscreen, here are a few other ways to reduce your exposure to these chemicals:
- Filter Your Water: PFAS are commonly found in tap water. Using a water filter that’s certified to remove PFAS can help reduce your intake.
- Avoid Non-Stick Cookware: Many non-stick coatings contain PFAS. Switching to stainless steel or cast iron can be a safer alternative.
- Choose PFAS-Free Products: From clothing to cosmetics, be mindful of the products you buy. Look for labels that clearly state they are PFAS-free. CleanProductList is a great resource for curated recommendations that help you make safer choices every day.
Final Thoughts: Protecting Your Skin Without the Risks
Sunscreen is essential for protecting your skin from the sun, but it’s important to be aware of what’s in the products you use. By choosing PFAS-free sunscreens, you can protect your skin and reduce your exposure to harmful chemicals. Next time you’re shopping for sunscreen, take a few extra minutes to read the labels to spot PFAS in sunscreen and make a choice that’s better for your health—and for the environment.
Remember, staying safe in the sun doesn’t mean you have to expose yourself to unnecessary risks. With a little knowledge and the right products, you can enjoy the sun while keeping both your skin and your health in the clear.
