Though there isn’t a single formal or scientific definition of reef-safe sunscreen, dermatologist Laurel Geraghty, MD, says that the time period is usually used to explain SPF merchandise made with out oxybenzone or octinoxate. Whereas there are a handful of different probably dangerous elements (as they relate to the ocean)—Benzophenone-1, Benzophenone-8, OD-PABA, 4-Methylbenzylidene camphor, 3-Benzylidene camphor, nano-Titanium dioxide, nano-Zinc oxide, and octocrylene, in accordance with the Nationwide Ocean Service—Geraghty says that oxybenzone and octinoxate are the primary focus because of Hawaii’s ban on them (which was proposed in 2018 and went into impact on January 1, 2021).


Octocrylene is a chemical sunscreen ingredient that, as soon as absorbed into the pores and skin, captures UV rays earlier than they’ll trigger injury to the underlying pores and skin cells. It could possibly additionally assist stabilize chemical sunscreen formulation.

Now that what reef-safe sunscreen will not be, let’s discuss what it’s. As Geraghty factors out, reef-friendly SPF is often formulated with zinc oxide, “a delicate, secure ingredient that gives broad-spectrum safety from ultraviolet gentle,” she explains. In contrast to nano-Zinc oxide, zinc oxide isn’t prone to hurt marine life or human cells and organs, making it a more healthy solar safety alternative.

Nonetheless, the knowledge we do have from current research does present that some UV filters are extra dangerous to coral reefs than others.

“There’s rising concern concerning the influence that people might have on the surroundings, and we’d like extra research to know simply how a lot of an influence our private care merchandise might have on our coral reefs,” Geraghty says.

Fortunately, many merchandise at the moment are labeled as “reef-safe” to assist make doing so extra approachable. That stated, since reef-safe sunscreens aren’t regulated, it helps to know which particular elements ought to be averted (and why). With that in thoughts, and to assist make your sunscreen buying so simple as attainable, under discover a complete checklist of the sunscreen elements you must keep away from to guard the ocean. In spite of everything, though dermatologists and the science world as a complete are pushing for extra research, what we already know is that coral bleaching is feasible, and that’s motive sufficient to start out altering our habits.
