Is Your Sunscreen Toxic? Debunking the Myths About Sunscreen Safety
When it comes to sunscreen ingredients, there's a lot of information—and misinformation—out there. With so many conflicting claims, it's hard to know what’s true. Is sunscreen toxic? Are some ingredients harmful? Let’s dive into the facts and clear up some common misconceptions.
As a father of three and a Sunscreen Evangelist who has been using and promoting sunscreen for over 30 years, I’ve heard it all. I’ve applied sunscreen daily and at countless events and trade shows, sometimes more than 100 times a day. If there were any detrimental effects, I’d be the test subject! Fortunately, I’m still feeling great, with over 1M applications over the last 30+ years.
Let’s separate fact from fiction and address the key concerns surrounding sunscreen safety.
Are Sunscreens Toxic? The Debate Explained
The conversation around sunscreen safety often centers on certain chemical ingredients. One ingredient that has raised concern is oxybenzone, which some studies suggest may act as an endocrine disruptor. However, many of these studies are based on animal tests with extremely high doses—far beyond what a human would be exposed to from sunscreen use.
For example, research on oxybenzone involved oral ingestion in mice, with doses so large that it would take a human 150-250 years of daily use to reach the same level. While some UV filter ingredients can penetrate the skin and enter the bloodstream, the FDA and dermatologists continue to endorse sunscreen use as part of a comprehensive sun protection strategy.
What the Science Says About Sunscreen Safety
Here’s what leading experts and recent studies have found:
- A 2020 review published in the International Journal of Dermatology concluded there is no conclusive evidence linking oxybenzone or octinoxate to health problems in humans.
- The 2021 European Commission’s Scientific Committee noted concerns about oxybenzone potentially disrupting hormones but emphasized that the data are “not conclusive.”
- Dr. Henry Lim, a past president of the American Academy of Dermatology, states that sunscreen ingredients have been used for decades without evidence of causing population-level health problems.
The FDA recommends continued sunscreen use to reduce the risk of skin cancer and premature aging. The negative effects of sun exposure are well-documented, whereas the potential risks associated with sunscreen ingredients remain uncertain and unproven.

What About Recent Concerns Over Benzene?
Another issue that has raised alarm is the benzene contamination found in some sunscreen products, including Banana Boat, Sun Bum, Coppertone, Aveeno, and Neutrogena. Benzene is not an ingredient in sunscreen but a contaminant that can occur during manufacturing. While benzene exposure is linked to health risks, not all sunscreens are affected, and many brands have implemented stricter testing to ensure product safety.
The Role of Oxybenzone in Sunscreen Safety
While some animal studies have linked oxybenzone to reproductive and hormonal disorders, it’s important to note that no conclusive human studies have shown harm at the levels used in sunscreen. The ingredient has even been found in the urine and breast milk of individuals who use UV-filter-containing products, but this does not automatically mean it causes health issues.
The American Academy of Dermatology, FDA, and Health Canada continue to approve the use of oxybenzone and other sunscreen ingredients due to their long history of safe use and lack of concrete evidence linking them to harm.
Expert Opinions on Sunscreen Safety
As Dr. Jennifer Beecker, a certified physician in dermatology and emergency medicine, points out:
"Everything in the world is a chemical, and many are harmless."
The key takeaway is that using sunscreen is a proven method to prevent sunburn, skin cancer, and premature aging. The benefits of sun protection far outweigh the potential risks of sunscreen ingredients, which have been used for decades without proven negative health effects.
Safe Sun Protection Practices: What You Can Do
While the debate about sunscreen toxicity continues, you can take these steps to minimize risks and protect your skin effectively:
-
Consider UV-Protective Clothing
- Wearing UV apparel and wide-brimmed hats can reduce the amount of sunscreen needed on exposed skin.
-
Avoid Peak Sun Hours
- Stay out of direct sunlight between 10 a.m. and 4 p.m. to avoid the most intense UV rays.
-
Find a Sunscreen You Like and Use It Consistently
- Choose a product that feels good on your skin, so you'll be more likely to apply and reapply it as needed.
