Discover the Truth: Is ‘Reef-Safe’ Sunscreen Truly Eco-Friendly for Our Oceans?

Some sunscreen you apply will make its way to rivers, lakes, or oceans. Even if you never go swimming, that sunscreen can still impact aquatic life. Experts warn that UV filters in these products might harm marine creatures.

Many brands claim their sunscreens are “reef safe,” but what does that really mean? To explore this, we spoke with dermatologists, ecologists, and chemical engineers to get a clearer picture of how to protect both your skin and the environment.

### Types of Sunscreen

There are two main types of UV filters in sunscreens: mineral and chemical.

Mineral sunscreens form a physical barrier on your skin, reflecting UV rays. On the other hand, chemical sunscreens absorb UV radiation and turn it into heat that your skin can release. Some chemical sunscreens are labeled “organic,” but this is a chemistry term, not an environmental claim.

### Sunscreen and Water

Statistics show that when you swim, about 25% to 50% of your sunscreen will wash off. The rest may end up in wastewater when you shower or launder your beach towels.

Dunia Santiago, a chemical engineer from Spain, explains that most treatment plants struggle to remove all traces of these UV filters. As a result, these chemicals can flow back into nature, accumulating over time. Many UV filters do not break down easily, meaning they can linger in the environment, settling in sediments and being consumed by marine animals.

### The Bigger Picture

This issue is not just about individual choices; it connects to larger environmental concerns. A 2021 study indicated that nearly 14,000 tons of sunscreen wash off into oceans each year, particularly impacting coral reefs, which are already stressed from climate change.

Social media trends show that consumers are increasingly looking for eco-friendly products. Many people are sharing their experiences with “reef safe” sunscreens, pushing brands to be more transparent about their ingredients.

By understanding these factors, you can make more informed choices about sun protection, safeguarding both your skin and our planet. For more detailed information, consider checking out authoritative sources like the Environmental Protection Agency.
