Travel sunscreen safety update: Which is the best sunscreen?
In 2019, a study in a respected medical journal released just in time for the “sun season” indicated many of sunscreen’s top ingredients are absorbed into your skin within 24 hours. And that made a splashy headline about sunscreen safety. Tweets and posts flew around cyberspace in a panic about finding the best sunscreen.
Although these ingredients are apparently absorbed, “The demonstration of systemic absorption well above the FDA guideline does not mean these ingredients are unsafe,” wrote editors at the Journal of the American Medical Association (JAMA) – since they just don’t know!
Also important when it comes to sun safety, especially for travelers, is the prevalence of skin cancers: Researchers noted that skin cancer is the most common malignancy in the United States, making using sunscreen (or wearing sun protective clothing) more important than not – especially if you are doing a lot of touring outside and in sunny months.
New proposed FDA rules for sunscreen safety
Despite the importance of choosing the best sunscreen and practicing sun safety for travelers, the United States Food and Drug Administration, which approves sunscreen, has been very slow in taking action. In fact, the last time it updated and improves guidelines was in 2011, which we wrote about in a then-apt named story, “Sunscreen confusion solved.”
Of course, it wasn’t really solved, and JAMA editors noted in the above editorial that accompanied the 2019 study on absorption that the FDA is stymied by the lack of real knowledge about sunscreen safety. (To be fair, the FDA did pass the so-called “Sunscreen Innovation Act” in 2014 to provide an alternative process to review the safety and effectiveness of sunscreens.)
Now, just in time for travel and sun season, the FDA in 2019 has also proposed another round of new regulations to increase sunscreen safety. The proposals include:
- Noting very clearly which ingredients are considered safe (only zinc oxide and titanium dioxide) and which are not generally considered safe and which do not have sufficient evidence to say.
- Delineating amounts to use and “dosage” for sprays, oils, lotions, creams, etc.
- Considering raising the highest SPF (Sun Protection Factor) allowed on labels from 50+ to 60+.
- Requiring broad spectrum protection.
- Mandating more understandable labels.
- Stating that sunscreens combined with insect repellents are not safe.
So what is the best sunscreen and how do I choose?
The truisms in our “Sunscreen confusion solved” story still hold true. Here are a few:
- If you are worried about chemical absorption, then stick to the only two ingredients considered safe: zinc oxide and titanium dioxide. Why are they considered safe sunscreen? They are natural and they only sit on your skin and act as a barrier.
- ONLY use broad spectrum for the ultimate in sun safety. The two ingredients above are just that in their protection from UVA and UVB rays.
- Go for at least 30 SPF but not necessarily 50+.
- Do not forget to reapply. Buy smaller tubes you can carry with you when traveling and touring so you can’t blame not having it along. And remember that NO sunscreen is waterproof.
- Do not use combinations like sunscreen and bug repellent.
- Wear sunscreen even in the shade, due to reflection.
- When it comes to the ingredients named in the JAMA study, you have to weigh out your preferences: These are in many popular sunscreens and make them “creamier” and easier to put on, to be honest. There is less of a tendency to turn your skin white or to have it caught up in arms hairs in white globs. The bottom line is, the best sunscreen for sun safety is in fact a sunscreen you will wear.
What about coral reef safety and sunscreen?
One hears constantly that sunscreen chemicals are not safe for coral reefs and are destroying them. Science does not seem to be conclusive on that, with the International Coral Reef Foundation even saying as much in a 2018 report. Nevertheless, the foundation still says to beware and continue to use so-called “reef-friendly” sunscreens (one factor is not including the ingredient oxybenzone).
One thing water lovers and reef lovers can do as a part of sunscreen safety around reefs is to cover up with sun-protective clothing rather than slathering the entire body with sunscreen.
