: All other authors declare no conflict of interest.
: All procedures performed in this study involving human participants were in accordance with the 1964 Helsinki declaration and its later amendments. Written informed consent was obtained from all individual participants included in the study. The human study was done with a cosmetic product already on the market using topical application. Cosmetics have to be safe products. European legislation has therefore produced positive and negative lists for the constituents of cosmetics. Cosmetic products manufactured according to cosmetic Good Manufacturing Practice (Cosmetic GMP) can be considered per se as safe for human testing. Therefore, no individual review by an ethics committee was deemed necessary for this study.
