Why you should be wearing mineral sunscreen

The best environment and skin-friendly sunscreens around

By now we all know the sun is nothing to joke about. Even if you’re in cloudy London, rather than on a beach in the Bahamas, you should be slapping on the SPF daily during sunlight hours. But not all sunscreen is created equal, and many creams and lotions available in pharmacies and supermarkets leave a lot to be desired in terms of their ingredients list. Some of the chemicals on there have not only been linked to skin irritations and allergic reactions, but can also damage the environment by bleaching waterways and killing coral reefs. 

What’s the damage?

Let’s take the environmental effects first. According to a 2015 paper published in the journal Archives of Environmental Contamination and Toxicology, up to 14,000 tons of sunscreen enter the world’s reefs annually, causing irreparable damage and killing life there. The main culprits in sunscreen are the chemicals oxybenzone, which absorbs UV rays, and octinoxate, which soaks up UVB rays. They enter the ocean by washing off beach goers, and filter into the water supply from showers and toilets, causing bleaching, deformities, DNA damage and ultimately death in coral reefs. This has led to Hawaii banning sunscreens that contain these chemicals, and last year Palau, a small island nation in the Pacific known for having one of the largest marine reserves on the planet, also implemented a ban. Other places like Bonaire in the Caribbean and Key West in Florida will no longer sell these sunscreens or allow their use from 2021.

The negative effects on human health are slightly cloudier, as no definitive tests have ever been carried out on the safety of oxybenzone and octinoxate, in addition to other ingredients found in chemical sunscreens like avobenzone and ecamsule. Although as yet not definitive, links have been made between these and severe allergic reactions, as well as significant uptake of these chemicals into the body from the skin, which could lead to hormone disruption and affect everything from users’ metabolism to their growth and development. The most recent scientific trial in May 2019 looked at the absorption of these ingredients into participants’ systemic circulation, and concluded that the U.S. Food and Drug Administration needed to carry out further non-clinical toxicology assessments, which would include tests for systemic carcinogenicity, as well as studies on their impact on human development and reproduction. 

Does this mean we shouldn’t wear sunscreen?

Because of the lack of evidence, the current advice given by the British Association of Dermatologists (BAD) emphasises that sunscreen should definitely still be used to protect the skin during sun exposure. ‘It is important to note there is no evidence from this study that there is any health risk,’ says Professor Brian Diffey of BAD. ‘And even at maximal use, any theoretical risk is almost certainly far smaller than the reduced risk of skin cancer that has been shown to be associated with sunscreen use. Indeed, the authors themselves say that their results do not suggest that people should refrain from using sunscreen.’

‘Skin cancer is the UK’s most common cancer, equalling all other cancers combined. The link between excess sun exposure and skin cancer is well documented and indisputable,’ continues Dr. Andrew Birnie, consultant dermatologist and skin cancer surgeon. ‘This research on sunscreen is very much at an early stage. The first line of defence against the sun should be shade and clothing, with sunscreen used for additional protection.’

The good news is that there are more and more sunscreens entering the market now that are both reef and skin sensitive, and avoid using the ingredients currently under investigation. Many of these are based on minerals like zinc oxide and titanium dioxide, which are considered ‘safe’ by bodies like the FDA and BAD, and provide physical protection by creating a barrier on the skin, and reflecting UV rays, rather than absorbing them. Here’s six mineral-based sunscreens that are good alternatives to traditional chemical creams.

Soleil Toujours 100 Per Cent Mineral Sunscreen SPF 30

Founder of Soleil Toujours, Valerie McMurray, was driven by her wish to avoid the potentially harmful ingredients found in most sunscreens. This mineral alternative features zinc oxide, which provides stable and safe protection against UVA rays, as well as aloe vera to heal and soften skin, skin soothing licorice root extract, and ubiquinone to help reduce the appearance of fine lines and wrinkles. A lightweight fluid, it’s easily absorbed into the skin.
