Abstract: Chinese made eye shadows (cosmetic commonly used by women and children) were analysed to determine the levels of heavy metals (Pb, Cd, Ni, Cu, Zn, Cr, Co, and Mn) in the products. Different samples of eye shadow were randomly selected from products available in the shops at Zaria, Kano and Kaduna markets in Nigeria. After digestion with concentrated acids (HNO3 and HCl), concentrations of the selected heavy metals were determined in triplicate using a flame atomic absorption spectrophotometer. Nickel, copper, zinc, cobalt and manganese were detected in all the colours of eye shadow in varying concentrations. Chromium was also detected in all the colours except one (Diamond pink). The regulations relating to cosmetics products gave no limit values for toxic elements such as metals occurring as impurities in cosmetics products. However, it has been proposed that the levels of nickel, cobalt and chromium should preferably be less than 170 μgg-1 and Lead should not exceed 20 μgg-1. 85% of the colours have Ni and Co concentrations above 170 μgg-1 but Cr concentrations were below this limit in all the colours. Only 2 brands (3 colours) have lead content higher than 20 μgg-1. 7 out of 20 colours (35%) of the brands of eye shadows contain cadmium at low concentrations. It is obvious from the present study that the use of facial cosmetics like eye shadow exposes users to low levels of heavy metals.

TL;DR: The findings indicate that one mechanism by which makeup and cosmetics alter facial appearances involves inducing visual illusions, and it is suggested that the eye size illusion caused by eyeliner, mascara, and eye shadow uses the same mechanism as that of the Delboeuf illusion, a geometric illusion of assimilation.
Abstract: Do eyeliner, mascara, and eye shadow actually make the eyes appear larger than they really are? If so, by what percentage? To answer these questions, we used psychophysical experiments. Experiment 1 manipulated the degree of eyeliner (four levels) and mascara (five levels), and measured perceived eye size using a psychophysical procedure called the staircase method. The results showed that both eyeliner and mascara make the eyes appear larger than they really are by up to 6% (13% in area), but their effects are not additive. Eyeliner increased perceived eye size only in the absence of mascara. In the presence of mascara, however, eyeliner has no additional effect. Experiment 2 measured perceived eye size with or without eye shadow and demonstrated that eye shadow increases perceived eye size by about 5% (10% in area). These findings indicate that one mechanism by which makeup and cosmetics alter facial appearances involves inducing visual illusions. In addition, it is suggested that the eye size illusion caused by eyeliner, mascara, and eye shadow uses the same mechanism as that of the Delboeuf illusion, a geometric illusion of assimilation.
TL;DR: The results suggest that the eye size illusion induced by the eyebrows and the Delboeuf illusion involve the same mechanism, and that eye shadow causes the assimilation of the eyes into itself and enhances assimilation between the eyes and the eyebrows.
Abstract: Does an assimilative illusion like the Delboeuf illusion occur in the human face? We investigated factors that might influence the perceived size of the eyes in a realistic face. Experiment 1 manipulated the position of the eyebrows (high or low), the presence/absence of eye shadow, and the viewing distance (0.6 m or 5 m), then measured the perceived eye size using a psychophysical method. The results showed that low eyebrows (i.e., closer to the eyes) make the eyes appear larger, suggesting that the assimilation of eyes into the eyebrows is stronger when the eye-eyebrow distance is shorter. The results also demonstrated that the application of eye shadow also makes the eyes look larger. Moreover, the effect of eye shadow is more pronounced when viewed from a distance. In order to investigate the mechanism of the eye size illusion demonstrated in Experiment 1, Experiment 2 measured the magnitude of the Delboeuf illusion at a viewing distance of 0.6 m or 5 m, with or without gray gradation simulating the eye shadow that was used in Experiment 1. The experiment demonstrated that the Delboeuf illusion is modulated by viewing distance and gradation in the same way as the eye size illusion. These results suggest that the eye size illusion induced by the eyebrows and the Delboeuf illusion involve the same mechanism, and that eye shadow causes the assimilation of the eyes into itself and enhances assimilation between the eyes and the eyebrows.
