But while these are the safest choice for our skin, traditional formulas can contain toxic chemicals such as oxybenzone and octinoxate which pollute seas and marine life. The Pacific island of Palau was the first nation to ban toxic sunscreen – it can’t be sold in shops nor can tourists bring it into the country. Hawaii, Key West, Bonaire, Aruba, the US Virgin Islands and several destinations in Mexico have also banned these chemical sunscreens. And with so many brilliant brands now becoming eco conscious, it’s an easy switch to make. Choose mineral-based sunblocks with zinc oxide or titanium dioxide and non-nano-sized particles which can’t be ingested by corals.
