2 safety concerns
1. Nanoparticles in cosmetics and sunscreen are a relatively new phenomenon and there is still some debate regarding the safety of them.
While some avoid “nano” altogether, others only stay away from nano-containing products that could be inhaled, such as sunscreen sprays.
The Organisation Friends of the Earth are among those very skeptical,
“Wearing sunscreen and protecting our skin from harmful UV rays is very important, but nano-ingredients in these products may be doing more harm than good to our environment and our health. … Despite a growing body of science calling their safety into question, our government has made little progress in protecting the public, workers and the environment from the risks posed by nanoparticles.
We urgently need FDA and EPA to step up and properly regulate and label these tiny and potentially harmful ingredients.”
2. Although, there is research showing that the physical sunscreen titanium dioxide is a carcinogen when inhaled, using it for example in cream is considered safe.
To be on the safe side, use sunscreen creams rather than spray or powder to avoid inhaling any harmful chemicals.
There are many dangerous chemicals in sunscreen that are known to cause negative effects on both humans and the environment. The chemicals are absorbed through the skin, our bodies largest organ, and then enters our bloodstream.
One of the biggest players in the world, the FDA, has recently published data (2019) that shows how sunscreen chemicals are being absorbed in potentially toxic levels by our bodies.
They found that people who had used sun protection (spray, lotion or cream) had dramatically increased levels of these chemicals in their bloodstream even 4 days after application. Levels that are potentially harmful, especially for pregnant women and young children, according to the FDA.
FDA has especially found clear safety issues with the sunscreen chemicals PABA and trolamine salicylate and does not consider them safe to use. The safety of 12 other sunscreen chemicals is still pending as the FDA waits for more data.

Dangers of sunscreen of this sort
Many chemical UV filters are known to cause:
- hormone disruption
- increased infertility
- and harm to marine life.
The negative effects these chemicals have on both humans and marine life are connected to their ability to disrupt hormones.
Almost half of all approved UV filters in traditional sunscreens interfere with the function of sperm by mimicking progesterone (steroid hormone). This can lead to the sperm failing to fertilize an egg.
Sunscreen chemicals can also damage marine life either when they are rinsed off and released in lakes and streams through the sewage system, or when they are spread directly in the water from our bodies when we go swimming.
The most famous example comes from Hawaii, who recently banned sunscreen chemicals oxybenzone (part of benzophenones) and octinoxate due to their harmful effects on marine life, ecosystems and coral reefs. But there are also cases in Europe where the chemicals we have on our bodies when we go swimming are damaging plankton and fishes.
