Q. I am a breast cancer survivor and have heard that some sunscreens contain estrogen-like compounds. I cannot have anything that contains estrogen in or on my body, so I would like to know any brands to avoid and which brands are safe.
A. Benzophenone-3, also known as BP-3 or oxybenzone, has estrogen-like activity. We suggest looking for sunscreen that has physical blockers such as titanium dioxide or zinc oxide. These have no known hormonal activity.
For more information about sunscreen safety and a list of our favorite products, we are sending you our Guide to Skin Care.
