Cosmetics are a staple in daily beauty routines worldwide, embraced for their role in enhancing personal appearance and self-care. However, their direct application exposes the skin to a range of ingredients, including metal(loid)s, and these can have a hazardous impact on human health if they exceed the limits defined by regulatory agencies. As a result, it is important to evaluate metal(loid) levels to ensure the safety of these cosmetic products. This research aimed to analyze several cosmetic products (massage cream, cleaner, mud mask, skin polish, scrub, lipstick, foundation, lotion, face powder, and highlighter) for metalloids (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, As, Sb, Cd, Pb, Bi, and Hg) by using inductively coupled plasma-optical emission spectrometry (ICP-OES). Multivariate and bivariate statistical approaches were used to interpret the sources and association between the metal(loid)s. The concentration ranges of metals were found to be Al (1.18–4.15 mg/kg), Cr (0.13–2.19 mg/kg), Mn (1.89–28.77 mg/kg), Fe (4.09–126.02 mg/kg), Co (0.19–31.62 mg/kg), Ni (0.11–5.39 mg/kg), Cu (0.08–0.19 mg/kg), Zn (1.99–47.81 mg/kg), Sr (0.99–10.34 mg/kg), Cd (0.16–1.50 mg/kg), Pb (0.29–2.44 mg/kg), Bi (0.23–2.18 mg/kg), and Hg (0.012–0.42 mg/kg), whereas the concentration ranges of metalloids were found to be As (0.011–0.051 mg/kg) and Sb (0.042–1.66 mg/kg). Among the tested cosmetic products for the metal(loid) levels, the estimation of the margin of safety (MOS 1), hazard index (HI > 1), and cumulative cancer risk (LCR ≤ 1 × 10−3) indicated non-carcinogenic and carcinogenic health risks associated with the use of few products. Most of the cosmetics products under investigation are safe with respect to non-carcinogenic and carcinogenic health risks. By highlighting the need to limit excessive use and adhering to sustainable safety practices, this study underscores the importance of monitoring and regulating metal(loid) content to ensure consumer safety and mitigate environmental impact.
