12 JOURNAL OF COSMETIC SCIENCE Our investigation, despite uncovering new insights about the additive effect of makeup on gaze and attraction, suffers from some limitations. First, the limited sample of viewers warrants investigation with bigger panels, although some of the findings (e.g., mascara boosting effect) could be replicated with a distinct viewing panel under two different conditions: with facial masks on and without masks. The stimuli used in this study being static, and more sophisticated methodologies using video or live eye-tracking, would further confirm the boosting effect upon gaze imparted by makeup. Lastly, the study was conducted with a selection of makeup, and care must be taken when extrapolating results for other makeup products/brands, although a similar effect can be expected with regard to color contrast, evening out of the skin, or enhancement of lashes’ appearance. It would be of value to also expand on other makeup products, for instance eyebrow pencils, although their use is not as widespread as mascara. Among other factors of interest worth investigating would be the impact of makeup finishes (e.g., satin, matte). Going forward, thoughts also turn to the idea of combining physiological measurements, such as heart rate, galvanic skin response, or pupillometry with eye-behavioral measurements, to further cement the links between gaze and perception to attractivity (16). CONCLUSION Our findings indicate that combined makeup product application (lipstick, foundation, mascara) may have a positive, incremental effect on gaze and perceived attraction versus bare skin (no makeup) or application of a stand-alone makeup product. This incremental effect may help to demonstrate the value of applying multiple makeup products to consumers and, in parallel, encourage postpandemic makeup product sales. Lipstick and mascara products were found to have the greatest “eye-catching” effect, with application of foundation showing the greatest impact on perceived health. However, no differences in terms of perceived age were observed in the present study. A rise in the need for consumers to look more attractive post–COVID-19 will likely see the comeback of daily multistep makeup routines, which have recently been neglected. The “boosting” effect of mascara may, however, also be observed when a face mask is worn.
