Sun creams: a hidden danger for our beaches this summer?

IN SHORT Introduction to the massive use of sunscreens in summer Impact onmarine ecosystem and the beaches Potential dangers of chemical ingredients in some creams Examples of adverse effects on wildlife and the aquatic flora Alternatives ecological And natural available Importance of sensitization beach users

As summer approaches, with our feet in the sand and the sun on our skin, we tend to consider sun creams as essential allies in protecting our skin from the harmful effects of UV rays. However, beneath the apparent benevolence of these products lies a disturbing reality: sunscreens can have devastating effects on our marine ecosystems. Corals, fish and all coastal biodiversity often suffer in silence from the chemical residues we leave behind after a day on the beach. This summer, it is crucial to explore this issue in order to become aware of the hidden dangers that we inflict on our coastlines, while thinking about alternatives that are more respectful of the health of our planet.

On the beach, it is crucial to protect yourself from UV rays to avoid sunburn and the risk of skin cancer. However, our actions to protect our skin could have harmful consequences on the marine environment.

A toxic cocktail for the oceans #

When applied to the skin, the sunscreens partially dissolve in water. This action releases chemical compounds that can be toxic to marine life. Studies have found that certain elements found in these creams, such as oxybenzone and octinoxate, have devastating effects on coral reefs.

Brands are going green, but is it enough? #

Sensitized by environmental issues, more and more cosmetic brands are turning to so-called “ecological” formulations. However, even though some of these new creams are less toxic, none of them can be described as completely neutral for the environment. This claim remains to be proven through rigorous independent laboratory testing.

Science addresses the problem #

In Nice, ten researchers are analyzing the impact of different sun creams on anemone cells, representative of the Mediterranean fauna. Their goal is to determine which products are actually less harmful. In the absence of strict regulations in Europe, these scientific tests are essential but are not sufficient to regulate the sun cream industry.

What can you do to protect your skin and the planet? #

• Opt for mineral sunscreens which use filters like titanium dioxide or zinc oxide. They are generally less toxic to the environment.
• Choose to wear protective clothing such as anti-UV t-shirts.
• Avoid exposing yourself to the sun during the hottest hours, between 11 a.m. and 4 p.m.
• Look for products certified by independent labels that guarantee a lower environmental impact.

Choosing sun protection which minimizes its impact on the environment requires an effort of research and vigilance. Consumers must decipher labels and favor alternative solutions to protect their skin without harming marine ecosystems.
