(NaturalHealth365)  We’ve all heard the mantra: wear sunscreen to protect your skin.  But recent research has uncovered a twist in this sun-safety tale that you need to know about.

For years, we’ve known that many products contain PFAS chemicals – synthetic compounds used for their water and stain-resistant properties.  These “forever chemicals” are found in everything from non-stick cookware to waterproof clothing, and yes, even in some skincare products.  But until now, we’ve been in the dark about how much of these substances actually get absorbed through our skin.

Let’s break down the latest findings and what they mean for your skincare routine.

Breakthrough study unmasks the skin-deep truth about forever chemicals

Scientists recently conducted a study that’s changing how we think about skin absorption.  They looked at 17 different PFAS chemicals found in many products, including some sunscreens and cosmetics.  Using a 3D model of human skin, they tested how much of these chemicals actually penetrate our skin barrier.

This is the first time we’ve had a clear picture of human dermal uptake of PFAS, and the results are eye-opening.

Here’s what they found:

1. Size matters:  Shorter PFAS chemicals are more easily absorbed.  For example, perfluoropentanoic acid (PFPeA) and perfluorobutane sulfonate (PFBS) had the highest absorption rates at 58.9% and 48.7%, respectively.  That’s more than half of what’s applied!
2. The longer, the better (sort of):  As the carbon chain in these chemicals gets longer, less of it is absorbed directly into the bloodstream.  But here’s the catch – it doesn’t just disappear.
3. Skin deep storage:  Longer-chain PFAS (those with 9 or more carbon atoms) might not enter your bloodstream directly, but they don’t just wash off either.  A significant amount ends up stored in your skin tissue.  For instance, 66.5% of perfluoroundecanoic acid (PFUnDA) and 68.3% of perfluorononane sulfonate (PFNS) were found hanging out in the skin tissue at the end of the study.
4. It’s all about chemistry:  The study found that how easily a PFAS is absorbed correlates with its water solubility.  The more water-soluble, the more likely it is to be absorbed.

What this information means for you

Now, you might be thinking, “Great, but what does this mean for my daily sunscreen application?”

1. Not all sunscreens are created equal.  Some contain PFAS chemicals, while others don’t.  It’s worth taking a closer look at the ingredient list on your favorite brand.
2. Absorption doesn’t equal harm:  While this study shows these chemicals can be absorbed, it doesn’t automatically mean they’re causing harm.  More research is needed to understand the long-term effects.
3. Consider your options:  Mineral-based sunscreens and other alternatives that don’t contain PFAS might be worth exploring.

Taking action

Armed with this new information, here’s what you can do:

1. Become an ingredient investigator:  Start checking those labels.  Look out for anything with “fluoro” in the name – that’s often a sign of PFAS.
2. Mix up your sun protection:  Consider using sunscreen with other sun-safety measures, such as wearing protective clothing or seeking shade during peak sun hours.
3. Stay informed:  This field of research is evolving rapidly.  Keep an eye out for new studies and recommendations.

Remember, taking care of your skin is about balance.  You’re now equipped with valuable information to make informed choices about your sun protection strategy.  Bottom line, don’t let this news scare you away from exposing your skin to the sun.  After all, getting out into the sun can do wonders for your mood and overall health.

As always, if you have specific concerns, don’t hesitate to chat with a well-educated healthcare provider.  They can help you navigate these new findings and find the best approach for your unique skin needs.

Editor’s note: Since many of our NaturalHealth365 readers wonder what I do for sun protection, here’s my point of view.

1. Living in Florida, I do spend a lot of time in the sun (playing pickleball, landscaping and jogging) but, I rarely use sunscreen and when I do – my wife gives me the Badger mineral (non-nano) zinc oxide product. (By the way, I do not receive any financial compensation for tell you this)
2. Keep in mind, I do have darker skin (due to my tan) and consume lots of antioxidants, on a daily basis – which gives me natural protection.
3. If I do feel like I’ll be in the sun for an extended period of time and want to get some extra protection … I’ll wear a hat, use an umbrella and/or wear long sleeve shirts to get some relief.
