Article Synopsis
- Hydroquinone, mercury, and arsenic were analyzed in skin-lightening cosmetics purchased from various stores in Ilorin, Nigeria, due to their hazardous health effects with long-term exposure.
- The analysis used UV-spectrophotometry for hydroquinone and atomic absorption spectrophotometry for mercury and arsenic, with results showing varying levels of these substances in all samples tested.
- Most samples exceeded safe limits, with only three containing permissible levels of hydroquinone; the study emphasizes the need for regular monitoring of these harmful chemicals in cosmetics sold in Nigeria.
