Oxybenzone has received a significant amount of negative press recently because of its damaging effects on coral reefs. In addition to environmental issues, there are a number of health concerns that have been raised about this common sunscreen ingredient. Specifically, oxybenzone is an estrogen mimetic, capable of disrupting normal hormone signaling in humans.

”The use of the two most common organic filters, oxybenzone and octinoxate, has recently been restricted in Hawaii due to their harmful effect on the coral reefs” (NIH.gov)

Hormonal Disruption by Oxybenzone
The molecular structure of oxybenzone is very similar to the hormone estrogen. In fact, it is close enough in shape that it is able to bind to estrogen receptors in cells in the body. One consequence of oxybenzone exposure is reduced levels of testosterone in both men and women.6 Higher levels of oxybenzone in the body may also alter the balance of thyroid hormones.7

Allergies and Skin Reactions Caused by Oxybenzone
Oxybenzone does not cause skin reactions in everybody who uses products with it. However, an uncommon but regular problem that oxybenzone can cause is photocontact dermatitis - an allergic-type reaction of your skin to the sun. In some people, the interaction of certain chemicals and sunlight causes a rash on their skin, and oxybenzone is a well-known perpetrator.8

Oxybenzone Causes Oxidative Stress in Cells
Along with other UV filters, oxybenzone does reduce the amount of UV-caused damage in your skin, and reduces the risk of sunburn and skin cancer. However, when exposed to UV light, oxybenzone itself can also generate reactive oxygen species (ROS). These oxidative molecules can cause damage to the DNA, proteins, lipids, and other structures within your cells. The number of ROS produced increases with the length of time that oxybenzone is left on your skin.5
