Bone mineral density is a crucially important index for skeletal health. A low amount of bone density (osteoporosis) is a common health problem among men and especially women. Among different parts of the body, women’s face is the area on which many types of (facial) cosmetics are routinely applied. The aims of this study were to measure the association of cosmetic use with BMD of the lumbar spine and femoral neck among young female students. This is a cross-sectional study on 65 female students in the 2017 academic year. The study participants were students at Shiraz University of Medical Sciences who were selected randomly using phone directory sampling method. Based on the results of multiple linear regression, adjusted for several important covariates, cosmetic use is inversely associated with the BMD z-scores. Lead was significantly associated with trochanteric z-score (B = −0.002 to 95% CI = −0.004 to −0.0003, p = 0.02) and total lumbar z-score (B = −0.002 to 95% CI = −0.004 −0.0005, p = 0.01). In the present study, duration of using cosmetics was significantly associated with BMD of key skeletal regions. The big market of cosmetics in many countries especially those in the Middle East is highly a vastly neglected health issue. Many more observational prospective or interventional studies are required to understand the benefits and hazards caused by cosmetics in women.
