Specific findings matter more than broad labels
When a sunscreen brand makes an environmental claim, look for the research behind it. Check the finished formula tested, the organisms studied, the concentration and exposure time, and the limitations reported alongside the results.
What our research covers
AETHIC’s formulation work includes coral experiments described in European patent EP2736482B1. A separate 2017 sea-urchin study tested a finished SPF40 sunscreen. It found no significant difference in embryo abnormalities at 24 hours compared with the control, while also reporting larval and enzyme effects.
The patent and study do not establish that every ingredient or current product is harmless to all marine life. A patent is also distinct from independent environmental verification.
A separate life-cycle comparison
The assessed SPF50 sunscreen showed lower impact in 11 of 16 environmental categories compared with two reference alternatives. The life-cycle assessment was independently reviewed, and SPF50 was admitted to the Water Revolution Foundation’s Hub of Verified Solutions. The scope of that comparison matters: it does not automatically verify other products.

For sun protection, use the directions on the product packaging and reapply as instructed. No sunscreen blocks all UV rays; use shade and protective clothing as well.
