Thin Layer Chromatography (TLC), used in forensic analysis, has many advantages: simple, cheap, and efficient. This study aimed to separate dihydroxybenzene isomers in whitening creams in the market and online shops using the BPOM label or not. Of the six eluent mixtures, this research used Toluene: Diethyl Ether: Acetic Acid with a ratio of 80:20:1 after optimization and validation test. In this case, the recovery percentages of resorcinol and hydroquinone were 51-66% and 80-87%. Of the 20 samples tested, 12 whitening creams were added with resorcinol, and 4 were added with hydroquinone. The addition of resorcinol and hydroquinone based on the regulation in Perka BPOM no 18 of 2015 was 5%. Furthermore, 2 out of 20 samples were added with hydroquinone within the regulated threshold, while the remaining 2% were accepted and the other six were undetected. In this case, adding hazardous substances has violated the rules of consumer protection laws and regulations.

Background: The COVID-19 pandemic is a devastating blow to the entire world community and changes the order of human life. Purpose: All efforts and strategies are being carried out to contain and reduce the spread of the SARS-CoV-2 virus by tightening the health protocol and using vaccines for the public. Currently, several vaccines are available and have passed phase 3 clinical trials, such as vector vaccines (Gamaleya Sputnik V Russia, University of Oxford/AstraZeneca, CanSino, and Janssen Pharmaceutical Companies), mRNA-based vaccines (Moderna/BioNTech/Fosun Pharma/Pfizer), inactivated vaccines (Sinovac and Sinopharm from China, Covaxin from Bharat Biotech India) and adjuvanted recombinant protein nanoparticles (Novavax from the USA), which are expected to be able to suppress the spread of the virus and produce a minimum of 70% herd immunity in a population. This study uses a narrative review from reputable publications and is closely related to the topic. Result: Each vaccine's efficacy varies from the lowest, namely, the Sinovac vaccine (CoronaVac) 50%, to the highest the Novavax vaccine (NVX-Cov2373) 96% effectivity value. However, further rigorous research is still being carried out to develop an effective and efficient vaccine. Health workers are the last bastion to handle COVID-19 patients. Conclusion: The primary purpose of the present immunization is to prevent and minimize the spread of COVID-19. At this time, the availability of a variety of vaccines is expected to provide strategic answers to the pandemic scenario that has afflicted countries all over the world.
