INTRODUCTION AND OBJECTIVES

Pigmentary disorders (PD) are frequent dermatological conditions, but little is known on their real-world prevalence and impact. This first worldwide survey evaluates the self-reported prevalence of PD such as Melasma, Post-inflammatory Hyperpigmentation (PIH), Solar Lentigo, Vitiligo, Peri-Orbital Hyperpigmentation (POH) and Axillary Hyperpigmentation (AH), their impact on quality of life (QOL) and stigmatization. We present here the results among people who had a diagnosis for their PD by a dermatologist (PDD) versus the ones who were diagnosed another way (self-diagnosed or by another HCP) (nPDD).
