How does a scuba diver choose a reef safe sunscreen?

Scuba women are exposed to the elements when diving, making sun care a necessity. UV rays reflecting off the water and wind increase the likelihood of sunburn. Passionate about scuba diving, I do not wish to harm the beautiful reefs I visit. I am conscious of what is on my skin and the potential damage it can do to the marine life and fragile coral reefs I admire. I also want a sunscreen that is safe for me, free of toxins that will nourish my skin and protect me from sunburn.

Suncare begins with seeking shade whenever possible, covering up and then finding a truly reef friendly sunscreen. Misleading, labels may mean we purchase a sunscreen claiming to be reef safe when the reality is it contains ingredients that harm our reefs. Searching for reef safe sunscreens can be confusing – natural mineral sunscreen? sport sunscreen? conventional chemical sunscreen? nano zinc oxide? non nano? zinc oxide? titanium dioxide? what are reef safe sunscreens? where does a scuba woman start?

Conscious of my fin print, I hope to remove the confusion when buying a reef safe sunscreen. As a scuba woman, I support brands that are helping save the oceans by manufacturing eco-friendly, reef-safe, sustainable, and ethical products. This post focuses on reef safe sunscreens from companies that live and breathe sustainability. Scuba women can shop with confidence knowing the brands below are trying to be better for our blue planet.

How does a scuba diver choose an ocean safe sunscreen?

Conventional chemical sunscreens create a chemical reaction under the skin, converting UVA and UVB rays into heat before releasing them. Chemical sunscreens containing oxybenzone and octinoxate deform young corals, damage DNA, disrupt reproductive cycles and endocrine systems, and cause coral bleaching; they are neither reef safe nor people safe.

“Slip, Slop, Slap”

I am a scuba woman living in Queensland and have spent many hours exposed to the sun. I love diving and being in the water, on the beach, and in boats. Early mornings and summer evenings are glorious, but the harsh midday sun can burn within minutes. As a senior scuba woman, I take sun protection seriously and try to avoid sun exposure between 10am and 3pm, but it is not always practical on a dive boat. Like many other scuba women, I turn to sunscreen.

As an Australian, I grew up with the “Slip, Slop, Slap” campaign by the Cancer Council. – “Slip on a t-shirt, Slop on some sunscreen, and Slap on a hat.” I seek shade, cover-up, and then turn to sunscreen. I “Slip, Slop, Slap,” though I insist the sunscreen lotion I use is safe for my body and the aquatic world I dive in.

How does a scuba diver choose a reef safe sunscreen?

Misleading, unregulated labels make it difficult to identify true reef friendly sunscreens. Understanding labels is imperative when buying a reef safe sunscreen. My mission is to help scuba women dive and shop with confidence. Googled over 100 000 times a month, finding a reef-friendly sunscreen needs to be easy. Many sunscreens claim to be biodegradable, green, natural, or organic, which does not mean they are safe for our reefs.

Protect our vulnerable reefs by using reef-safe sunscreen

The chemicals in conventional sunscreens threaten up to 10% of the world’s reefs. Always read the label and boycott sunscreens containing oxybenzone (benzophenone-3), octinoxate, homosalate, and avobenzone when choosing a sunscreen.

Showering, swimming, snorkeling, scuba diving, surfing – 14 000 tons of sunscreen washes into our coral reefs yearly. A living organism, coral reefs provide shelter for thousands of marine animals, regulate carbon dioxide levels in the ocean, stabilize the ocean floor, filter water, and prevent coastal erosion by storm surges. I feel compelled to protect this intricate world.

A broad spectrum sunscreen offers the best protection, meaning the sunscreen reflects or absorbs at least 90% of the UV rays. A mineral sunscreen creates a barrier between your skin and the sun. A chemical sunscreen absorbs the rays under your skin, creating a chemical reaction.

A reef-safe sunscreen will not contain chemicals, nano particles, parabens, phthalates, artificial fragrances, or colors. When looking at your ingredient list, it is essential to look for non-nano particles. Nano particles are tiny particles that can leach into the water and hurt delicate ecosystems.

Everything a scuba diver needs to know about reef safe sunscreen

Mineral sunscreens are the safer option, forming a barrier on your skin to reflect UVA & UVB rays. The active ingredients in mineral sunscreen are non-nano zinc oxide or titanium dioxide. They are recognized by the FDA to be safe and effective.

The Hawaiian-based, not-for-profit Haereticus Environmental Laboratory (HEL) sets the standard for reef-safe sunscreen and personal care products. If a sunscreen displays the Protect Land & Sea certification seal, it has been rigorously tested and found reef safe. HEL is making companies accountable for the ingredients they use and continue to randomly test to ensure companies are maintaining reef-safe standards.

The mineral sunscreens below are broad spectrum, protect and nourish your skin, and are safe for our oceans and all that dwell within them. Cover up as much as you can, and apply sunscreen as necessary. Read the label. A good sunscreen’s active ingredients will be either non-nano zinc oxide or titanium oxide. Look at the botanicals and antioxidants in the non-active ingredients and choose your favorites to nourish your skin while protecting it from the sun.
