Phthalates also can be found in various other cosmetics, including some soaps, shampoos, nail polishes and hair sprays, and parabens are in many hair care and make-up products

These compounds aren’t just in sunscreens, either. However, this effect has only been found in very high doses. This could lead to problems later in life, such as reduced sperm count or increased risk of testicular cancer. High-level exposure to phthalates, in particular, has been found to disrupt development of male genitals. Laura Vandenberg, associate professor at the University of Massachusetts Amherst's School of Public Health and Health Sciences, says most endocrine disrupters affect male foetuses and embryos. But no research on humans has backed this up. Some lab and mice studies have found that some organic UV filters, including oxybenzone, as well as ingredients including parabens and phthalates, which can be found even in sunscreens that use inorganic UV filters, are suspected endocrine disrupters: chemicals that interfere with our hormones.

However, the trial was very small – involving only 24 people.

“Little is known about systemic exposure for most active ingredients” in sunscreens, the FDA stated in its report, referring to the effects of large volumes of sunscreen absorbed through the skin and into the body.įDA scientists authored a paper focusing on four ingredients found in sunscreen into the skin, including oxybenzone, and concluded that absorption of sunscreen into the body may be more than a theoretical concern. This alone doesn’t mean sunscreen is unsafe, but there is growing focus on the potential adverse effects of the most common UV filter worldwide: oxybenzone. It’s long been established that some organic filters are absorbed through the skin and into the bloodstream.

The ‘silent killer’ of Africa’s albinosīut some researchers have raised concerns that, despite being an undeniably important tool in our fight against skin cancer, the formulation of sunscreen may need to be improved to contain safer ingredients – and, at worst, some sunscreens could be damaging our health.

“Countries where rates are falling have had the biggest investments in communicating awareness, such as New Zealand, Denmark, the US and Australia.” “Skin cancer rates are increasing among older generations – they’re carrying damage from decades earlier in their lives, because things have changed now,” says Adele Green, senior scientist of the cancer and population studies group at QIMR Berghofer Medical Research Institute in Australia. This is why, although skin cancer is rising in some countries, it’s decreasing in others – particularly those that have raised the most awareness around the importance of using sunscreen. “Any conversation on sunscreen must start with acknowledging that there is robust evidence that it prevents skin cancer,” says Richard Weller, honorary consultant dermatologist at the University of Edinburgh. And one of the most effective ways to avoid it, of course, is sunscreen. In the US alone, cases of non-melanoma skin cancers have grown by around 77% over the past two decades.Įxposure to UV radiation is the main cause of the most common forms of skin cancer. Rates of non-melanoma have increased too. Since the early 1990s, rates of melanoma in the UK have increased among every age group. It’s also one that – while still the least common form of skin cancer – is rising in prevalence around the world. Melanoma is one of the deadliest cancers.
