Evaluation of the UV absorbance of sum skin lighting creams

Abstract

The results of studies conducted on some skin-lightening creams in the Saudi market indicated that they contain heavy metals in varying proportions that exceed the limits recommended by the World Health Organization, which may cause danger to human health. The study focused on three types of skin-lightening creams, namely Fair & Lovely, Rose, and Diana, to estimate their absorption percentages. In general, the results showed that the relationship between the absorbance rate of skin lightening creams and the wavelength is an inverse relationship, where the absorbance rate decreases with the increase in wavelength. For samples treated with ferment only for skin-lightening creams, the cream with the highest absorption value was Fair & Lovely cream, and the lowest absorption value was Rose cream. In addition, for untreated cream samples, Rose cream had the highest absorption, while Fair & Lovely cream recorded the lowest absorption value. In addition, the samples of creams to which olive oil was added only, without exposure to any other factors, had almost the same absorbance value. Moreover, the samples of creams that were exposed to sunlight varied in their absorbance values, as Rose cream recorded the highest absorption value and Fair & Lovely cream had the lowest absorption value. In the samples of creams that were exposed to X-rays, the results showed that the Diana cream sample and the Rose cream sample had the same pattern and behavior in absorbance.UV spectroscopy (Genesys 10S UV-Vis spectrophotometer) was used.
