Shielding Our Skin and Seas
Why does creating a more environmentally friendly sunscreen matter? Imagine swimming in the ocean, surrounded by vibrant coral reefs and diverse marine life. Now, picture those same reefs bleached and lifeless due to chemicals we use daily. The quest for sunscreens that protect us without harming marine ecosystems is not just about avoiding sunburn; it's about preserving our planet's underwater biodiversity. Studies, like the one presented by Craig Downs, have sparked a global movement to rethink the ingredients in sunscreens, leading to bans on harmful substances like oxybenzone. This shift towards safer alternatives is crucial for our health and the health of countless marine species. For you, it's an opportunity to engage with science that directly impacts our environment and future. This topic might inspire you to think about how everyday products are developed and their broader implications on our world.

Ecotoxicologist
A scientist who studies how toxic chemicals affect ecosystems, animals, and plants.

Photodegradation
The breakdown of molecules caused by exposure to light, which can reduce the effectiveness of sunscreen ingredients.

Mycosporine-like amino acids (MAAs)
Natural compounds found in marine organisms that protect against UV radiation and have antioxidant properties.

Antioxidant
A substance that prevents damage to cells caused by free radicals, unstable molecules that can harm cellular structures.

Carotenoids
Pigments found in plants and algae that can absorb UV light and protect against sun damage.

Polyphenols
A type of compound found in plants (including some marine plants) that can absorb UV rays and have anti-inflammatory and anti-photoaging properties.
