Cosmetics are applied widely by women and men for different proposes mainly beauty and skin care. However, the biologically active substances which are used in these products and their health effects are not fully known. The aims of this study were, first, to estimate the prevalence of cosmetics use, and second, to examine if any association exists between cosmetic use and serum levels of lead and cadmium (two heavy metals with major health effects) among young women. This is a cross-sectional study conducted on 65 female students during the first semester of 2017 academic year. Study sample was selected randomly using phone numbers. About 70% of the study participants started using cosmetics under age 20 years (about 14% under 15), and 50% were using the products on a daily base. After adjusting for possible confounders, significant associations were found between the participants age (B = − 0.0008, CI = − 0.001 to − 4.71, P = 0.03) and duration of using cosmetics (B = 0.0006, CI = 0.0001 to 0.115, P = 0.01) with the level of cadmium in their serum samples. Duration of using cosmetics (B = 0.008, CI 0.001 to 0.01, P = 0.01) was the only variable which was significantly associated with serum level of lead in the participants. According to the results of the present study, most Iranian girls start using cosmetics at a very young age making them more vulnerable to the potential hazards of the ingredients of cosmetic products including heavy metals and preservatives. The association between duration of using cosmetics and serum level of lead and cadmium may cause serious health problems for women at young ages and their fetus or children via placenta and breast milk. The big market of cosmetics in many countries especially Middle East is highly important.
