Toxic UV Filters in Sunscreen What Every Surfer Needs to Know

If you’re into surfing or love outdoor water sports, you know how important it is to protect your skin from the sun. But have you ever stopped to think about what's actually in your sunscreen? Many sunscreens on the market contain harmful ingredients—some of which can damage your skin, the environment, and even the oceans we love. In this post, we’ll take a closer look at the dangers of outdated UV filters, why they’re harmful, and how Aiguadolç’s new generation of sunscreen offers a safer, eco-friendly alternative.

Not all UV filters are created equal. In fact, some of them can cause more harm than good. Let’s take a closer look at the two main categories of UV filters and how they affect your skin and the environment.

Mineral (Physical) UV Filters: These include zinc oxide and titanium dioxide, which absorb and convert UV rays into heat, just like chemical filters. They are known for being safe for the skin and environment, but they can feel heavy, greasy, and leave a white cast—something many surfers and athletes find impractical.

Chemical/Organic UV Filters: This category includes both outdated UV filters like octocrylene (which may cause health and environmental concerns) and modern, safe UV filters that are photostable, non-toxic, and environmentally friendly. These newer filters absorb UV rays efficiently without breaking down into harmful by-products, making them the best choice for long-lasting and reef-safe sun protection.

Using sunscreens with outdated or low-quality chemical/organic UV filters can have negative effects beyond just sun protection. Here’s why it matters:

Skin Irritation & Sensitivity: Some outdated chemical UV filters degrade under sun exposure, forming by-products that can irritate sensitive skin. This can lead to redness, rashes, and even allergic reactions. (Sun allergies are often caused by low-quality sunscreen ingredients, not the sun itself!).

Harm to Marine Ecosystems: When sunscreen washes off in the water, it doesn’t just disappear. Harmful chemicals like oxybenzone and octinoxate have been proven to damage coral reefs and marine life. These chemicals can contribute to coral bleaching, disrupt ocean ecosystems, and harm marine animals. In fact, places like Hawaii have already banned sunscreens containing these harmful chemicals.

Hormonal Disruption: Some chemical UV filters, like octocrylene, have been linked to hormonal disruption, raising concerns about long-term health effects. Over time, these ingredients can accumulate in your bloodstream, potentially causing long-term health issues. This is especially concerning for anyone spending extended periods of time in the sun, like surfers.

At Aiguadolç, we use a new generation of modern, safe chemical/organic UV filters that are photostable and do not break down under UV exposure. Our formulas are designed to protect both your skin and the environment, avoiding the harmful ingredients commonly found in conventional sunscreens.

Additionally, our sunscreen is reef-safe, meaning it contains no UV filters that damage marine ecosystems. It offers long-lasting protection without compromising on safety, performance, or sustainability.

When you're out catching waves, you need sunscreen that performs. Here’s why Aiguadolç stands out:

• SPF 50+ Broad-Spectrum Protection: Shields against UVA (aging) and UVB (burning) rays.
• Lightweight & Quick-Absorbing: No greasy residue or white cast, perfect for active surfers- so you can get back to the surf without any discomfort.
• Hydrates & Strengthens the Skin Barrier: Works alongside our After Sun Care, which helps replenish moisture and repair the skin after sun exposure.
• Eco-Friendly Packaging: Our mono-plastic dispenser is fully recyclable, unlike multilayered plastic packaging that cannot be processed. We chose this material because it’s the most environmentally responsible option
• Reef-Safe & Non-Toxic: No ingredients that contribute to coral bleaching or pollute the ocean.

At Aiguadolç, we go beyond sun protection. Our formulas are vegan, cruelty-free, and developed with eco-conscious materials and ingredients.

Unlike many brands that use outdated and potentially harmful UV filters, we invested in a new generation of photostable filters that are safe for you and the environment.
