Systematic ReviewBackground: As the usage of social media has dramatically increased in a few decades it has affected the field of cosmetic dermatology. Social media can help to improve patient care and a cosmetic dermatologist can use social media to eliminate false information that spreads online. However, the majority of patients prefer to take advice from a nondermatologist rather than a certified dermatologist which negatively impacts patients' healthcare and the doctor-patient relationship. Objective: it was to find out how social media usage can impact the field of cosmetic dermatology and what challenges cosmetic dermatologists face while using social media platforms. Methods: We performed a literature review using papers from PubMed and many other resources involving social media platforms, including Facebook, Twitter, Instagram, YouTube, WhatsApp, and blogs. Results: There are not enough clinical trials done to conclude whether the usage of social media is a pro or a con. A cosmetic dermatologist can face ethical challenges like protecting patients' rights to privacy and autonomy. Also, research has shown that top posts related to cosmetic dermatology and articles written by a board-certified dermatologist are in a small percentage.
