Spotting fake news: a qualitative review of misinformation and conspiracy theories in acne vulgaris

Acne vulgaris is an extremely common disorder of the pilosebaceous unit, typically manifest as a highly visible facial and upper trunk dermatosis, with teenagers most frequently affected. This cohort is markedly susceptible to misinformation, given their impressionable age, distress about their appearance and high internet usage. This study aimed to assess the content of acne‐related misinformation available online. A formal review of PubMed was performed in March 2022, using the terms ‘acne’ AND ‘misinformation’ OR ‘disinformation’ OR ‘conspiracy theory’, along with an informal Google search using combinations of these terms, and further targeted searches on TikTok, Twitter, Facebook and Instagram. Key themes of acne‐related misinformation included diet and other ‘causes’ of acne, unconventional acne ‘cures’ and a distrust of conventional acne treatments. Websites promoting misinformation were frequently affiliated with companies selling products that promised to cure acne, often in a remarkably short time. Dermatologists should be aware of the nature of acne‐related misinformation available online and be prepared to counter it with scientific principles and facts.
