Summertime is perfect for enjoying the great outdoors and soaking up some vitamin D. However, many people turn to sunscreen to protect their skin from the sun’s rays, potentially exposing themselves to toxic chemicals. One particularly harmful ingredient commonly found in sunscreen is benzophenone, also known as oxybenzone. While these chemicals block out ultraviolet light, they have been known to cause physiological side effects.
The Effects of Benzophenones
A study conducted by the New York State Department of Health revealed that benzophenones can mimic the actions of the hormone estrogen and increase the chances of developing endometriosis in women. Endometriosis is a painful condition caused by uterine tissue growing outside the uterus.
When using sunscreens containing benzophenones or similar chemicals, some of it can be absorbed through the skin and enter the bloodstream. The researchers found that women with higher levels of these chemicals in their bodies were more likely to be diagnosed with endometriosis.
Allergic Reactions from Sunscreen
Benzophenones can also cause allergic reactions, such as skin rashes. In 2014, these chemicals were named Allergens of the Year by the American Contact Dermatitis Society. These dermatologists pointed out that benzophenones were initially designed to preserve varnish and paint. However, these chemicals have become common ingredients in a variety of personal care products, including hair dyes, nail polish, shampoos, conditioners, hand sanitizers, and perfumes.
Environmental Impact
Besides posing a threat to human health, sunscreens containing these toxic chemicals can be harmful to the environment. When these sunscreens wash off into oceans, lakes, and rivers, they can damage aquatic life.
Choosing a Safe Sunscreen
In order to find a sunscreen that is both effective and free of harmful chemicals, consult the Environmental Working Group’s (EWG) website. They provide a comprehensive directory of the safest sunscreens on the market.
Rather than solely relying on sunscreen for protection, it’s important to get a sufficient amount of sun exposure to allow the skin to produce vitamin D. After that, consider using clothing and hats to shield yourself from the sun’s harmful rays. But, if you do decide to use sunscreen, make sure it’s a safe one.
When selecting a sunscreen, consider the following factors:
- Look for sunscreens with high SPF (Sun Protection Factor) values. A higher SPF value indicates greater protection against the sun’s harmful rays.
- Choose sunscreens containing physical blockers, such as zinc oxide or titanium dioxide. These ingredients sit on top of the skin and reflect the sun’s rays, offering a safer alternative to chemical sunscreens.
- Check the product’s label for harmful chemicals, like benzophenones and oxybenzones. To make it easier, refer to the EWG’s website for their list of safest sunscreens.
- Select a sunscreen that is water-resistant, as these products will last longer on the skin. However, remember to reapply after swimming or sweating, as no sunscreen is completely waterproof.
- Opt for broad-spectrum sunscreens, as these products protect against both UVA and UVB rays. UVA rays can cause premature aging, while UVB rays can lead to sunburns. Both types of rays have been linked to skin cancer.
By doing your research and choosing a safe sunscreen, you can enjoy the great outdoors without subjecting your skin to harmful chemicals or damaging the environment.
