#GOOD SUNSCREEN FOR FACE SKIN#

While nanoparticles can be absorbed by coral reefs, research suggests that larger non-nanoparticles (a label you’ll see on lotions) are better for the environment.

It’s worth remembering, though, that some research suggests zinc oxide can also pose a danger to marine life.

“Mineral sunscreens rely on inorganic filters, which form a physical barrier on the skin surface,” explains Dr Mahto. Mineral sunscreens, which typically contain zinc oxide and titanium dioxide, are thought to be less harmful to coral reefs in comparison to their chemical counterparts. “Many of the filters have also been found in various species of fish worldwide - the impact of this is uncertain on the food chain.” Opt for a mineral sunscreen instead “Certain organic filters have been identified in water sources worldwide and there seems to be a suggestion that they are not easily removed by common wastewater techniques,” adds Dr Mahto. Octocrylene is another chemical that’s potentially harmful to marine life, with the Haereticus Environmental Laboratory compiling a handy list of the ingredients we should try to avoid. “We demonstrated that oxybenzone, octinoxate and enzacamene caused complete coral bleaching even at very low concentrations,” says Professor Corinaldesi.

The main chemicals to watch out for are oxybenzone and octinoxate, which are commonly used in sunscreen to absorb UV light. While the science around exactly how damaging sunscreen is to our oceans is inconclusive, what ingredients should we be looking out for to make the best choice possible? We speak to marine biologist Professor Cinzia Corinaldesi from the Università Politecnica delle Marche and Dr Anjali Mahto, consultant dermatologist at Skin55, for a five-step guide. Another factor to consider in your sunscreen selection is its effect on the environment.
