ABSTRACT
Objective: We sought to evaluate the impact of the coronavirus-19 (COVID-19) pandemic on sun-seeking and sun-safe behaviors. Methods: We conducted an online, cross-sectional, population-based survey. Results: In total, 1,001 respondents participated in the survey and reported being exposed to 12 or more hours of sunlight (i.e., direct and indirect ultraviolet light, and blue light) each day. Participants self-reported a net increase in all types of light exposure since the onset of the COVID-19 pandemic, especially to blue light (+38%). Notably, while the effects of direct sunlight were well known among survey respondents, they were less aware of the potential damaging impact of indirect sunlight and blue light. Limitations: As the survey was only conducted among residents of the United States, results might not be generalizable to all geographical regions. Conclusion: Social outreach strategies are required to improve sun-safe behaviors. Future behavioral interventions should encourage the implementation of broad-spectrum sun protection.

Background. Droplet simulation often requires expensive and inaccessible equipment. Herein, we develop and assess a low-cost droplet simulation model using easily accessible materials, open-source software, and a smartphone-based cobalt blue light. Methods. The simulation model was developed using commercial-grade materials and fluorescein dye. A clear face shield was assessed ten times following a simulated cough using fluorescein dye. A conventional ultraviolet Woods lamp was compared to a smartphone-based cobalt blue light to detect fluorescein illumination. Results. The simulation platform and smartphone-based cobalt blue light cost $20.18. A Wilcoxon signed rank test revealed that the median droplet area of fluorescence under the UV Wood's lamp was not significantly different than that of the smartphone-based cobalt blue light (2.89 vs 2.94, P = .386). Conclusions. This simulation model is inexpensive and easily reproducible. The smartphone application may be a convenient alternative to standard ultraviolet lights. This model has great potential for use in financially restricted academic centers during the COVID-19 pandemic and beyond.

As COVID-19 vaccinations begin, dermatologists must be aware of the cutaneous adverse events reported in the clinical trials, including injection site and hypersensitivity reactions, and emerging evidence of dermal filler injection reactions after vaccination. The filler reaction may represent the development of a delayed-type hypersensitivity in the setting of another immunologic trigger (i.e., the vaccine). After conducting a literature review of similar reactions, their pathophysiology, and management, we present a set of timely clinical considerations for counseling, prevention, and management of possible cutaneous sequelae of the COVID-19 vaccine. We encourage documentation of vaccine-related reactions to aid the safety data collection in the Vaccine Adverse Event Reporting System and the American Academy of Dermatology COVID-19 Registry.
