Avobenzone is often touted as being unstable in the presence of sunlight. Although this is true when avobenzone is examined on its own, chemists who formulate with sunscreen ingredients know avobenzoneÕs pros and cons. As such, they can formulate with this UV filter in ways that improve its stability in sunscreens, such as using antioxidants and UV filters like octocrylene. A newer formulary strategy is encapsulation technology that also works to keep the UV filter where it's needed most the skin (21, 22).
