Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. It helps prevent sunburn. Avobenzone works by absorbing the rays and converting them to energy that is less damaging to the skin.

Dibenzoylmethane (DBM), a minor ingredient in licorice, is a calcium chelator that binds calcium through the β-diketone moiety, and it has been found to increase intracellular calcium concentrations in skeletal muscle cells. Intracellular calcium regulates the binding of Nrf2 to the HO-1 enhancer region. Both Nrf2 and HO-1 have been proposed as potential drug targets to prevent or treat liver disease. Thus was suggested DBM could be a lead/candidate for prevention or treatment of liver diseases. In addition, was found, that dibenzoylmethane inhibits mammary tumorigenesis, lymphomas, and leukemias in mice and it can prevent the formation of tumor-inducing DNA adducts.
