Whether you are heading to warmer climates or enjoying sunshine at home, wearing sunscreen is crucial, especially with melanoma skin cancer cases at an all-time high. However, some sunscreens contain ingredients harmful to the environment, and certain destinations have even banned them.
In 2015, a study revealed that a popular chemical UV filter found in many sunscreens is toxic to oceans, coral reefs, and marine life. Further research has identified other damaging chemical filters, commonly remembered as the “three Os”: oxybenzone, octinoxate, and octocrylene.
Finding an eco-friendly formula can be challenging without reading ingredient labels. Terms like “reef-safe” or “reef-friendly” are not officially regulated, so they cannot always be trusted. The best choice is mineral sunscreens using zinc oxide and titanium oxide filters, also known as physical sunscreens, which sit on the skin’s surface and reflect UV rays.
Mineral sunscreens may also be better for your skin. Dr Adil Sheraz, consultant dermatologist, explains: “Unlike chemical sunscreens, there is little chance of mineral products causing skin irritation – especially if you suffer from acne, eczema or sensitive skin.” However, not all mineral formulations are equal. For an eco-friendly option, look for non-nano or coated ingredients, as nanoparticles can also be toxic to the environment.
We tested the latest eco-friendly formulas for a minimum of five days, evaluating ease of use, feel, and finish. All are mineral formulations with non-nano ingredients, ensuring they are environmentally friendly.

Reef-Safe Sunscreen FAQs
Why choose a reef-safe sunscreen?
Dr Ross Perry, medical director of Cosmedics Skin Clinics, explains: “The biggest concern about SPFs for the planet is the pollution that it does to the oceans, thus affecting the ecosystem of these delicate environments.” The Ocean Foundation estimates 14,000 tons of sunscreen are deposited in oceans annually, endangering marine organisms and contributing to coral bleaching.
What is a reef-safe sunscreen?
“Reef-friendly” and “reef-safe” are not regulated terms. Generally, eco-sunscreens are natural alternatives using non-toxic ingredients like zinc oxide and titanium dioxide. Dr Perry advises: “When looking for a coral-friendly sunscreen, ideally, you’re looking for ones that don’t have oxybenzone and octinoxate ingredients.” Look for SPF 30+ for UVB, HEV filters for blue light, and a five-star UVA rating.
What are the skincare benefits of eco-sunscreen?
Dr Lakhani, cosmetic doctor at Harley Street’s Cranley Clinic, says: “Eco-sunscreen is particularly suitable for people with sensitive skin or skin conditions such as eczema. Also, if you’re prone to sun rash or other issues like prickly heat, eco-sunscreen can be particularly beneficial.”
Which destinations have banned certain sunscreens?
Tourist hotspots including Hawaii, Florida’s Key West, parts of Thailand, Mexico, and the Caribbean have banned certain chemical sunscreens. Switching to eco-friendly formulations helps avoid fines and protects local waters.
