Question What is the maximum plasma concentration of active ingredients of various types of sunscreen formulations under maximal use conditions?
Findings In this randomized clinical trial that included 24 healthy participants and application of 4 commercially available sunscreen formulations, maximum plasma concentrations (geometric mean [coefficient of variation]) for the active ingredient avobenzone were 4.0 (60.9%), 3.4 (77.3%), 4.3 (46.1%), and 1.8 (32.1%) ng/mL for 2 different sprays, a lotion, and a cream, respectively.
Meaning The systemic absorption of sunscreen active ingredients supports the need for further studies to determine the clinical significance of these findings./.../
