THE CRISIS
Why it Matters
Common sunscreen chemicals are devastating coral reefs worldwide. Even small amounts can cause bleaching, DNA damage, and death in marine organisms.

Coral Bleaching
14,000 tons of sunscreen enter coral reef areas each year. Oxybenzone causes coral bleaching at concentrations as low as 5 parts per billion.

DNA Damage
Chemical sunscreen ingredients damage coral DNA and reproductive systems, preventing reefs from recovering from stress.

Marine Life Harm
Chemical filters impair fish neurological and reproductive abilities, increase disease rates, and act as hormone disruptors that impact immune systems.

It’s Not Just the Ocean at Risk
YOUR HEALTH
It’s Not Just the Ocean at Risk
If you use chemical sunscreen, it's not just on you—it's in you. Over 90% of people tested by the CDC had oxybenzone in their urine. Sunscreen chemicals are absorbed through skin and have been found in breast milk.
The FDA recently proposed removing all over-the-counter chemical sunscreen ingredients from their 'Generally Recognized as Safe and Effective' list due to insufficient safety data and potential hormone disruption."

FAQ
Common Questions
Yes. Non-nano zinc oxide and titanium dioxide provide broad-spectrum UVA/UVB protection. They work by physically blocking rays rather than absorbing them.
Mineral sunscreens sit on top of skin rather than absorbing. Look for "tinted" or "sheer" formulas. The slight tint is a trade-off for ocean safety.
Most outdoor retailers, natural grocery stores, and online.
No. Sunscreen chemicals wash into waterways, lakes, and rivers through wastewater. Choosing reef-friendly sunscreen helps all aquatic ecosystems!
