Coral Reef Awareness Week & Why Your Sunscreen Matters – COTZskincare

It's Coral Reef Awareness Week (July 20–26, 2026), and if you're still reaching for a chemical sunscreen because it "blends better," we're going to hold your hand while we say this, but we need you to stop.

Because here's the thing no one tells you at the big makeup retail stores: some of the most popular sunscreens on the market are quietly dissolving the coral reefs you're probably posting pics of on your next beach trip. Yikes!

What is Coral Reef Awareness Week?

Coral Reef Awareness Week happens every year during the third full week of July, and it's exactly what it sounds like: seven days dedicated to spotlighting how fragile (and honestly iconic) coral reefs are, and what we can actually do to keep them alive.

Why Do Coral Reefs Actually Matter?

We know, "save the coral" can sound like a far-off, not-my-problem kind of cause. It's not. Here are the receipts:

They're disappearing fast. Major reef systems like the Great Barrier Reef have already lost a significant share of their coral cover to bleaching events driven by warming ocean temperatures, and scientists warn the majority of reefs worldwide could be under serious threat within the coming decades if current trends continue.

They're an entire ecosystem's apartment building. Roughly a quarter of all marine species rely on reefs for food, shelter, or breeding grounds at some point in their life cycle, despite reefs taking up less than 1% of the ocean floor.

They protect the coastline you're vacationing on. Reefs act as a natural barrier, absorbing wave energy before it slams into beaches and coastal communities. Fewer reefs means more erosion, more storm damage, and more risk for the people who actually live there.

They're a major food and economic engine. Fishing industries and coastal tourism, the very beach trips we're all planning, depend on healthy reef systems to function.
They've quietly contributed to modern medicine. Compounds found in reef-dwelling organisms have been studied for use in treating everything from cancer to chronic pain, making reefs a literal source of undiscovered medical breakthroughs.

Reefs aren't just pretty backdrops for your vacation story. They're infrastructure for the ocean, the coastline, and, honestly, us. Losing them isn't a "someday" problem. Bleaching events are already wiping out large portions of major reef systems worldwide.

The Sunscreen Connection Nobody Talks About

Here's where it gets personal: certain chemical UV filters, specifically oxybenzone and octinoxate, wash off your skin the second you get in the water and have been shown to contribute to coral bleaching, DNA damage in coral, and disrupted growth. Multiply that by literally millions of beachgoers slathering on sunscreen every summer, and it adds up fast.

The fix isn't "stop wearing sunscreen" (please still wear sunscreen, skin cancer is not the vibe). The fix is choosing a formula that skips those reef-harming chemicals altogether.

How Is CoTZ Actually Reef-Friendly?

This is our whole thing, not just a marketing checkbox.

CoTZ literally stands for Contains Only Titanium and Zinc. Since 2002, every formula has been built exclusively on mineral UV filters, titanium dioxide, and zinc oxide, with zero oxybenzone, zero octinoxate, and none of the chemical filters linked to reef damage.

Instead of absorbing into your skin (and eventually the ocean), mineral sunscreen sits on top of your skin and physically reflects UV rays away. Translation: better for your skin barrier, better for the reef you're swimming next to.
