Despite the increasing popularity of social media, the activity of dermatology residency programs on top social media platforms has never been investigated to our knowledge. We investigated a total of 126 dermatology residency programs to assess their presence and popularity on social media. Searches were conducted to identify dermatology residency departments' accounts on Facebook, Twitter, and Instagram. The number of Facebook likes, Twitter followers, and Instagram followers were recorded. Of the 126 dermatology residency programs, 29 (23%) were active on Facebook, 14 (11%) on Twitter, and 9 (7%) on Instagram. There was a wide range in the number of Facebook likes, Twitter followers, and Instagram followers. The top ten dermatology residency programs with the highest Facebook likes, Twitter followers, and Instagram followers were charted. Our results demonstrate the sparse usage of social media by dermatology residency programs. Although social media continues to increase in prevalence, dermatology residency programs are underutilizing these valuable resources.

Because YouTube is one of the most popular search engines, it is an instrumental tool to stay up to date on the most relevant dermatology trends and content in order to better direct patients and improve health outcomes. Twelve select terms (i.e. Dermatology, Sun protection, Skin cancer awareness, Skin cancer, Skin condition, Sun safety, Tanning, Melanoma, Basal cell carcinoma, Squamous cell carcinoma, Skin cancer treatment, Skin cancer prevention) were searched on YouTube. Overall, the results included 240 videos with over 160 million views. Educational content was most prevalent at 35% of the total search results. Of the total videos, 42% were uploaded by or featured a medical health professional (MD, DO, PhD, RN, ND), with 28% involving a board-certified dermatologist. Trends in content type have changed: educational and personal videos have increased, while advocacy and advertising have decreased. Most search terms are moving in a positive, informative direction, specifically the term "tanning." Other search terms such as "skin condition" and "skin cancer treatment" should be more closely monitored for misleading and perhaps harmful information. Therefore, dermatologists and other medical personnel should keep pace with relevant and popular dermatology content on YouTube in order to understand, advise, market, educate, and address patients' questions and concerns.

Owing to the COVID-19 outbreak, the use of telemedicine applications has increased throughout the United States. Using an algorithm to analyze mobile application rankings, we were able to examine how applications with telemedicine services have increased in prevalence and rank pre- and post- COVID-19. Telemedicine apps saw an increase of 210.92 ranked positions on average. Within US telehealth, skin conditions have become the fifth most common diagnosis. Widespread use of teledermatology has been well-accepted. Dermatologists and patients report high satisfaction using teledermatology during COVID-19 and intend to continue using these services in the future. COVID-19 has assisted in reducing physician concerns previously preventing some dermatologists from utilizing teledermatology in their services. Additionally, the geographical and socioeconomic barriers preventing some patients from receiving dermatologic care have been minimized through the use of teledermatology. Addressing these obstacles for dermatologic care improves healthcare equity.
