How to avoid oxybenzone
Avoid oxybenzone by reading ingredient labels. Be sure to avoid products that contain oxybenzone as well as oxybenzone synonyms (see above for a list of other oxybenzone ingredient names). Avoid sunburns by wearing protective clothing or using an umbrella [2]. Use mineral-based, toxic chemical free sunscreens whenever possible rather than chemical ones.
