A randomized clinical trial with 48 healthy volunteers assessed the absorption of six active ingredients (avobenzone, oxybenzone, octocrylene, homosalate, octisalate and octinoxate) in four sunscreen products formulated as lotion and sprays (aerosol, nonaerosol and pump). This study builds on a prior trial from Food and Drug Administration (FDA) researchers published by JAMA in 2019.
