BACKGROUND: Acne keloidalis nuchae (AKN) is an inflammatory disorder primarily seen in individuals of color, characterized by acneiform and keloidal lesions on the occipital scalp/nuchal region. More than 50% of patients with keloids are known to search their condition on the internet. We sought to determine the level of readability of patient education materials (PEM) available to patients. The term 'acne keloidalis nuchae' was searched and screened for the top 100 search results on the Google® search engine. For evaluation, 6 readability metrics (Flesch-Kincaid grade level, Gunning Fog index, Coleman-Liau index, SMOG index, automated readability, and Linsear Write Formula) were collected by entering text from each reference site into an automatic readability calculator for computation. Median readability scores of AKN PEMs ranged from 10.3th to 13.5th grade levels. Overall, readability median above the 8th-grade level were consistently seen across all 6 readability measures, with some median scores reaching university undergraduate levels. More readable educational tools are needed for acne keloidalis nuchae online. J Drugs Dermatol. 2023;21(2):195-196. doi:10.36849/JDD.7110.
