Inflammatory dermatoses, such as atopic dermatitis (AD), seborrheic dermatitis (SD), and contact dermatitis (CD), are among the most prevalent chronic skin diseases globally, significantly contributing to the burden of nonfatal diseases. 1,2These conditions are characterized by chronic inflammation, recurrent flares, and substantial impairment in quality of life, primarily due to pruritus, sleep disturbances, and psychosocial stress.Despite their high prevalence, comparative epidemiological assessments across major global economies remain limited.The Group of Twenty (G20) countries, which encompass a significant portion of the global population and health expenditure, are crucial for understanding global disease patterns.Utilizing data from the Global Burden of Disease Study 2023, we evaluated the burden of AD, SD, and CD across G20 countries from 1990 to 2023 and projected trends up to 2050.Data on incidence, prevalence, disability-adjusted life years (DALYs) and years lived with disability (YLDs) were obtained from the Global Burden of Disease Study 2023 database 1 .Age-standardized rates were used for comparisons across countries, sexes, and age groups.Temporal trends from 1990 to 2023 were analyzed, and projections through 2050 were generated using autoregressive integrated moving average (ARIMA) time-series models.Subgroup analyses were conducted by sex and age.
