The presence of dermatological information on social media has grown exponentially over the last two decades. Consequently, the recent literature on this topic is abundant. Many authors have highlighted that social media constitutes a unique opportunity for patient education. Additionally, numerous other benefits of these platforms have been reported. However, other authors have focused on the potential risks that these networks involve. The main concerns are patient confidentiality, legal considerations, and ethical issues. Therefore, we stand at a crossroads where the many advantages of social media use in dermatology seem to be underestimated due to the presence of potential drawbacks. At this point, we propose that a systematic review of the positive and negative aspects of using social media in dermatology is necessary. We carried out a comprehensive systematic review dating from inception to July 2021. Finally, 161 articles were included. Fifteen benefits, 11 drawbacks and 10 challenges of social media use in dermatology were identified and discussed. Suggested strategies to address the identified drawbacks were provided. Overall, while there are risks to using social media, they are outnumbered by their benefits. Therefore, dermatologists should embrace this opportunity to educate patients and aim to create rigorous and engaging content.
