The Future of Sunscreen: Inspired by Cephalopods

Octopus and squid pigments enhance sunscreen without harming the environment, Northeastern researchers and company founders say

Harnessing the Power of Cephalopods: A Breakthrough in Eco-Friendly Sunscreen

Inspired by Cephalopods

When we think of creatures with the most impressive camouflage abilities, cephalopods—octopuses, squids, and cuttlefish—are undoubtedly the masters. Their ability to change color and blend into their surroundings has fascinated scientists for decades. But beyond their artistry in disguise, these creatures hold a potential that could revolutionize something many of us use every day: sunscreen.

Researchers Camille Martin, a graduate from Northeastern University, and associate professor Leila Deravi, have tapped into this hidden potential. Their work is not about creating color-shifting technology, but something much more practical and vital: environmentally friendly sunscreen.

The Problem with Traditional Sunscreen

Sunscreen is one of our primary defenses against the harmful rays of the sun. However, many traditional sunscreens contain chemical UV filters that can be toxic to both humans and the environment. Some of these chemicals can create reactive oxygen species that may seep into our skin, causing systemic toxicity. These toxic ingredients also wash off into the ocean, where they can harm marine life, particularly coral reefs.

Given how much sunscreen ends up in oceans due to beachgoers, there’s a pressing need to develop a sunscreen that is both safe for humans and the environment. And this is where the cephalopods come in.

Xanthochrome: A Game-Changer from the Ocean

The answer may lie in a compound called xanthochrome. This trade name represents a bio-identical version of xanthommatin, a naturally occurring molecule found in the skin of cephalopods. Martin and Deravi were able to isolate this molecule and study its properties. What they discovered is nothing short of remarkable.

Xanthochrome is a powerhouse. It has antioxidant properties that are beneficial for human skin and is biocompatible, meaning it won’t pollute the environment. This makes it an ideal ingredient for sunscreen, as it provides protection without the negative impact traditional sunscreens can have on marine ecosystems.

More than Just Protection from the Sun

The multifunctional nature of xanthochrome is one of its most exciting features. Beyond UV protection, it acts as a free radical scavenger, which is essential for maintaining skin health and barrier function. This means xanthochrome not only shields the skin from the sun but also helps repair and protect it from everyday environmental damage. When combined with zinc oxide, an FDA-approved sunscreen ingredient, xanthochrome’s effectiveness is amplified. In fact, its ultraviolet protection increases by 28%, while its ability to block visible light jumps by 45%.

Octopuses – The Secret to Better Sunscreen

Martin and Deravi see this molecule as the next big thing in skincare, on par with other widely used ingredients like hyaluronic acid and retinoids. And the best part? It’s safe for both humans and the oceans.

The Future of Sustainable Skincare

As Martin points out, the beauty industry is increasingly looking for innovative, sustainable materials. Xanthochrome fits that bill perfectly. Not only does it offer effective protection, but it also aligns with the growing demand for products that don’t harm the environment. Deravi emphasizes that any new sunscreen product needs to be safe for people and the planet because, eventually, everything we put on our skin will end up in the ocean.

With the research published and the product development underway, it’s only a matter of time before xanthochrome-infused sunscreens hit the market. This innovation represents a significant leap forward in both skincare and environmental protection, proving once again that nature often holds the keys to solving our most pressing challenges.

In the race to create safer, more effective sunscreens, the cephalopods may just have provided us with the ultimate solution. The next time you apply sunscreen, you might be using a product inspired by the ocean’s finest masters of disguise.
