146 Prevalence of rosacea in transgender and gender diverse populations: A retrospective cohort study

Hormones have been shown to affect the pathophysiology of rosacea, however, the prevalence of rosacea in transgender and gender diverse (TGD) patients on gender affirming hormone therapy (GAHT) has never been studied. Our retrospective cohort study showed a significantly decreased prevalence TGD patients on feminizing GAHT compared to cisgender men, women, and TGD not on GAHT. Our results suggest that estrogen and/or anti-androgenetic agents may play a protective role in the development or course of rosacea.
