Abstract
Introduction: Pigmentary disorders (PD) are frequent dermatological conditions, but little is known on their real-world prevalence and impact. This first worldwide survey evaluated 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. Methods: This survey (N= 48,000) was conducted in 34 countries from all continents from December 2022-February 2023. The online auto-administered questionnaire covered demographics, phototype, self-reported pigmentation condition based on a descriptive text and image of each condition, its impact on QOL, stigmatization, and sun protection behavior. Results: 50% of the population (average age : 44 years) reported having at least one PD (solar lentigo 27%, AH 18%, PIH 15%, POH 15%, melasma 11% and vitiligo 8%), with more women affected (59%). Previous dermatological diagnosis was reported in 36% of them, while 19% made their own diagnosis thanks to the questionnaire. All PD significantly impact QoL and lead to stigmatization. DLQI score was >10/30 for 28% of them, and 44% of patients with a PD have concealed/hidden the visible parts of their affected skin. Although sun exposure worsens the pigmentation, respondents reported a low-level of protection against the sun: only 38% protect their skin all year long, and only 38% consider that sun exposure is deleterious to their condition. Conclusions: This first large international survey on PD shows the high prevalence of PD worldwide, their significant impact on QoL and stigmatization, highlighting the need for education on photoprotection.
