Every time we choose sun protection, we make a choice that goes beyond our skin.
A sunscreen does not simply disappear after application. During swimming, sweating, showering, or beach activity, parts of what we apply can wash off and eventually enter water systems. And when that water connects back to rivers, seas, and the oceans, the conversation around sunscreen becomes bigger than SPF.
It becomes a conversation about “RESPONSIBILITY”.
The invisible journey of sunscreen
Most people think of sunscreen only in terms of protection: SPF, PA rating, UVA, UVB, tanning, sunburn, pigmentation, and photoaging.
And rightly so. Sunscreen is essential for skin health.
But World Ocean Day asks us to look beyond the surface.
Because the same product that protects us under the sun may also interact with the world around us after it washes off. In coastal regions, beach destinations, reef zones, and high-tourism areas, this question becomes even more important.
What happens to sunscreen after it leaves the skin?
That question has become a growing area of scientific research.
Why are coral reefs part of this conversation?
Coral reefs are often called the rainforests of the sea.
They shelter marine life, protect coastlines, support fisheries, and help sustain ocean biodiversity. They are living ecosystems : delicate, complex, and deeply sensitive to environmental stress.
But coral reefs are already under pressure.
Rising sea temperatures, climate change, pollution, coastal development, overfishing, and tourism are all adding stress to reef systems. In ecosystems that are already fragile, even smaller local stressors can matter.
This is why researchers have been studying sunscreen UV filters and their possible impact on corals and aquatic life.
What research says about sunscreen UV filters?
Research over the last few years has raised concerns about certain UV filters used in sunscreens and their possible effects on coral health.
A 2021 review published in Environmental Sciences Europe noted that several studies have implicated sunscreen UV filters in negative effects on corals and possible contribution to regional coral decline. The same review also discussed how filters such as Oxybenzone and Octinoxate/OMC became part of sunscreen bans in regions including Hawaii, Palau, and the U.S. Virgin Islands.
The paper also makes an important point: the phrase “reef safe” is not clearly regulated. That means brands need to be careful, evidence-led, and responsible in the way they communicate ocean-friendly claims.
More recently, a 2025 study in Marine Pollution Bulletin tested the effects of three sunscreen formulations on hard and soft corals from the Maldives. The study found that different sunscreen formulations can affect coral species differently, with some exposed corals showing effects such as tissue loss, pigmentation loss, and polyp retraction.
The takeaway is clear: sunscreen formulation matters.
Not every formula behaves the same way. Not every claim should be treated the same way. And not every “reef-friendly” message is enough without scientific thinking behind it.
Why OMC and Oxybenzone are part of this conversation?
OMC, also known as Octinoxate, and Oxybenzone are UV filters commonly discussed in the context of coral reef and marine ecosystem concerns.
These filters have been associated in scientific and regulatory discussions with concerns around coral bleaching, coral stress, and marine-life impact. That is why they have received attention not only from researchers, but also from regulators in several reef-sensitive regions.
For consumers, this does not mean sun protection should be avoided. Sunscreen remains important for protecting the skin from UVA and UVB damage.
The real question is not whether we should use sunscreen.
The better question is: can sunscreen be formulated more thoughtfully?
Qurez’s approach: protection for skin, respect for the sea
At Qurez, suncare is built on a simple belief: what protects your skin should not come at the cost of the planet.
Qurez sunscreens are crafted without OMC and Oxybenzone filters often associated with concerns around coral bleaching and marine ecosystem stress. Our approach is to create reef-conscious formulations that offer effective daily sun protection while being mindful of the ecosystems our choices eventually touch.
From broad-spectrum SPF protection to wearable textures and more responsible biodegradable packaging choices, Qurez believes beauty should not leave a burden behind.
This World Ocean Day, we stand for sun care that protects more than skin.
We stand for coral reefs that continue to thrive, marine life that continues to move freely, and oceans that continue to breathe, heal, and sustain life.
Because conscious suncare is not just about what goes on your skin.
It is also about what goes back into the world.
Protect your skin. Respect the sea.
