Oxybenzone
What is Oxybenzone?
Oxybenzone is an organic compound used as an ingredient in many sunscreens. It functions as a UV filter, absorbing ultraviolet (UV) radiation and converting it into less harmful heat, which helps prevent skin damage.
The use of oxybenzone in sunscreen is primarily to protect against sunburn and reduce the risk of skin cancer. However, there is ongoing debate about its potential environmental impact, particularly its effect on coral reefs. Some studies also suggest that oxybenzone may act as an endocrine disruptor, although findings are mixed and more research is needed.
When you see oxybenzone on a label, it's often in the context of products designed for sun protection. It is important to weigh its protective benefits against potential risks, especially if you're concerned about environmental effects.
