Choosing the right sunscreen for your beach vacation is an important part of ensuring you don’t return home with a painful sunburn. But research suggests that in some cases, the sunscreen you’re using to protect your skin could be causing damage to the ocean’s coral reefs.
Octinoxate and oxybenzone, also known as benzophenone, are common ingredients found in chemical sunscreens that protect your skin by absorbing UV rays. Recent studies show both are toxic to coral by causing endocrine disruption and adding to coral bleaching, a phenomenon in which colorful coral turns white by rejecting symbiotic organisms.
While octinoxate and oxybenzone are effective in protecting your skin from the sun’s harmful rays, evidence suggests it can run off the skin and into the oceans as you swim. According to a 2017 Cosmetic Surgery Forum presentation by dermatologist Dr. Matthew Zirwas, a study conducted in the Virgin Islands found that a harmful concentration of oxybenzone was found in the waters in areas with a higher number of daily swimmers, typically in bays and coves closer to the shore.
So, what should you do if you want to help protect ocean coral?
You might think an easy answer would be to avoid wearing any sunscreen at all when you swim in the ocean, but that will leave your skin vulnerable to sunburns, future signs of aging like wrinkles and dark spots, or worse, skin cancer. Not a good idea. Fortunately, you do have some coral-safe sunscreen options.
Sunscreens with mineral-based active ingredients (also known as physical sunscreens), block the sun’s rays, as opposed to their chemical-based counterparts that absorb rays. While active ingredients found in physical sunscreens like titanium dioxide and zinc oxide can leave a white “cast” on your skin, they are shown to have less of a harmful effect on ocean coral.
Board-certified dermatologist Dr. Joel Schlessinger advises, “To keep your skin safe on vacation, choose a sunscreen with at least an SPF 30 and re-apply every two hours while you’re in the sun. Consider adding Heliocare, an antioxidant pill made from a fern in Central America as an added layer of protection. Additionally, try to add protective clothing where possible and keep under cover when you can, whether you are on a boat or on a hammock.”
