When we think about traveling more responsibly, we often think of eco-friendly stays, reducing our waste, or offsetting flights. But there’s one simple, everyday habit that has a huge impact on the environment: applying sunscreen.

And yet, we really need it. Whether you're lounging on a beach in Asia, hiking in Patagonia, or exploring a volcano, sun protection is essential. So how do we take care of our skin without polluting the ocean or harming marine life?

🌊 Sunscreen: An Invisible Source of Pollution

Each year, over 14,000 tons of sunscreen end up in oceans and seas. When we swim, shower, or sweat, part of our sunscreen washes off into the water. The result? Coral bleaching, fish disruption, and damaged marine ecosystems.

The main culprits are certain chemical UV filters found in conventional sunscreens — even those sold in pharmacies.

❌ Harmful Ingredients to Avoid

Here are the most toxic ingredients commonly found in sunscreen. Check the INCI list (usually in tiny print) on the back of the bottle:

• Oxybenzone (benzophenone-3)
• Octinoxate (ethylhexyl methoxycinnamate)
• Octocrylene
• Homosalate
• 4-Methylbenzylidene camphor
• PABA
• Parabens, silicones, and non-encapsulated nanoparticles

These substances can disrupt marine life, contribute to coral bleaching, and some are even banned in places like Hawaii or French Polynesia.

How to Choose a More Eco-Friendly Sunscreen

It’s not always easy to read an ingredient list, so here’s a simple guide to spot better alternatives:

Check the ingredients:

Mineral filters only:

• Zinc oxide
• Titanium dioxide
  Make sure they are labeled non-nano to prevent absorption by marine organisms.

🌱 Check for these labels or certifications:

• “Reef-safe” or “Ocean-friendly” (note: not an official certification, but a good indicator)
• Cosmos Organic
• Ecocert
• Cosmebio
• Natrue
• Biodegradable
• Free from endocrine disruptors

Avoid sprays:

Spray sunscreens waste a large amount of product in the air and increase the risk of particles reaching the environment — without protecting your skin properly. Choose creams or solid sticks instead.
