Background: Social distancing due to the pandemic is accelerating the fragmentation of Korean society in the megatrend of continuous individualization after industrialization. In this context, consumers are turning to direct-to-consumer (DTC) genetic testing for tailored skin healthcare strategies. However, there are still concerns about the safety of personal information in DTC genetic testing. The purpose of this review article is to examine the sustainable safety of DTC genetic testing for customized dermatology products, focusing on skin healthcare market after coronavirus disease 2019 (COVID-19).

Methods: A systematic review approach was used in this study. Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) flow chart, a total of 920 references were selected from PubMed, Medline, and Scopus. The composition of a total of 59 references from professional papers was finally reviewed. To this end, the most relevant recent literature was added, and the reference period was limited to 2018 to 2023 based on a 6-year period.

Results: With the practice of mask wearing since COVID-19, various methods are being used to strengthen the skin's immune system, and maintain and promote skin health. There is a need to have a method to increase the safety of DTC genetic testing for sustainable skin healthcare market.

Conclusions: It is concluded that there is a need to continue to develop more sustainable and safer security applications (apps) in the field of customized dermatology cosmetics to address the privacy issues and improve the accuracy of DTC genetic testing.
