Use of Skin-Whitening Products by Sudanese Undergraduate Females: a Survey
Journal of Racial and Ethnic Health Disparities, 2017Co-Authors: Anwar E. Ahmed, Mohamed E. HamidAbstract:Background Although Skin-Whitening products are commonly used among dark-Skinned women of African descent, research on the frequency with which Sudanese women use Skin-Whitening products is lacking. Methods A cross-sectional study was conducted at the University of Gezira, Sudan, on the use of Skin-Whitening products among a sample of Sudanese undergraduate females (ages 16–33 years). Sociodemographic characteristics were collected, and students were asked whether they had used Skin-Whitening products in the past 12 months. Results Of the 348 undergraduate females surveyed in this study, 74.4 % reported using Skin-Whitening products within the past year. Of this group, 2.7 % reported using injections, 2.4 % pills, 30.6 % bleaching cream, and 76.2 % soap. Illegal sources (e.g., people selling on the sides of roads) of Skin-Whitening products were reported by 22.8 %. The use of Skin-Whitening products was common in females who were not satisfied with their Skin colors more so than those who were satisfied with their Skin colors (83.7 vs. 70.5 %, P = 0.010). Undergraduate females who had mothers, sisters, or other relatives who bleached reported a greater frequency of using Skin-Whitening products than those who had no family member who bleached (100, 87.7, or 77 % vs. 67.5 %, P = 0.003, respectively). The odds of using Skin-Whitening products in females who had mothers or sisters bleaching were 7.8 times higher (adjusted odds ratio (aOR) 7.8; 95 % confidence interval (CI) 2.572, 23.828) and two times higher in females who had other relatives bleaching (aOR 2.4; 95 % CI 1.159, 5.115), compared with females who had no family members who bleached. Conclusion It was estimated that a majority (7 out of 10) of Sudanese undergraduate females have tried Skin-Whitening products. However, because the university population is an elite group, a population-based survey is warranted to address the use of Skin-Whitening products among the general population of Sudanese women.

The Skin Whitening industry in the Philippines
Journal of Public Health Policy, 2014Co-Authors: Roger Lee MendozaAbstract:Skin Whitening is a big and booming industry in many developing countries. Its popularity owes mainly to post-colonial, internalized racism. This study examines whether government intervention is necessary and more efficient than market-driven approaches in addressing the health risks and harms associated with Skin Whitening. We gathered empirical data on the quality and quantity of health-related information about Skin whiteners with a multi-stage probability sample of consumers in two cities in the Philippines ( n =110; α =0.05). Regardless of their socio-demographic characteristics, we find that cognitive biases and information asymmetries build and sustain consumers’ trust in manufacturers and distributors of Skin whiteners while, paradoxically, breeding uncertainties over the integrity of these products. The results are product adulteration and misbranding, leading to pricing advantages for toxic whiteners over safer products. This has impeded regulatory efficacy. We recommend anchoring government intervention in transaction cost-reduction, containing the externalities of Skin bleaching, and institutionalizing third party partnerships. Failure to do so would leave consumers extremely vulnerable to the forces of supply and demand that favor toxic whiteners, particularly in a market where voluntary collective action is difficult to organize.

Skin-Whitening Activities of Lactic Acid Bacteria Lactobacillus Rhamnosus
Transylvanian Review, 2017Co-Authors: Hyeon Yong LeeAbstract:Aim: This work was to investigate Skin-Whitening activities of lactic acid bacterium, Lactobacillus rhamnosus . Materials and methods: Lactobacillus rhamnosus isolated from Kimchi, a Korean traditional fermented vegetable was grown in MRS medium for 48 hours at 37’C, and then collected by a centrifuge at 8000rpm. The cells were extracted by an ultrasonification extractor with 140 kHz at room temperature. Then, the cell free extracts were lyophilized for the experiments. Results: The intracellular cell-free extracts showed strong antioxidant activity as 15.27% of 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging ability, and 16.11% of tyrosinase inhibition and 53.90% of melanin synthesis inhibition were also observed. These activities were similar to or even better than those from other natural plant herbs. It was also found that there was a close correlation between antioxidant activities and Skin-Whitening activities of the extracts. Conclusion: It was first shown that the extracts from Lactobacillus rhamnosus had relatively high Skin-Whitening activities, which could be used as an alternative natural Skin-Whitening agent.

Skin-Whitening and UV-Protective Effects of Angelica gigas Nakai Extracts on Ultra High Pressure Extraction Process
The Korean Journal of Medicinal Crop Science, 2008Co-Authors: Cheol-hee Kim, Minchul Kwon, Hyeonggeun Kwak, Geunpyo Choi, Ukyeon Park, Jae-gun Han, Hyeon Yong LeeAbstract:This study was performed to investigate the enhancement of UV-protection activities and Skin-Whitening effects from Angelica gigas Nakai extracts on ultra high pressure extraction process. Extraction at treated by ultra high pressure for 15 minute and associated with ultrasofication (HPE15) was showed more than double yield, compare conventional extraction, as 12.24% (w/w) from A. gigas. Extracts of HPE15 reduced expression of MMP-1 on UV-irradiated CCD-986sk cells as 122.2% and revealed high inhibitory potency on tyrosinase as 69.4% by adding samples. Extracts of HPE15 from A. gigas showed strong inhibition effect on melanin production test by Clone M-3 cells as 82.4% by adding extracts. From the preliminary observations, we considered that the extracts from A. gigas could be potent natural materials for Skin-Whitening agent, and could be used as a potential anti-aging agent for the photo-damaged Skin.
