Expert perspectives on the nature of atopic dermatitis, ranging from diagnosis and pathophysiology to the clinical and social burden it places on patients.

In our first Irregular Borders column, Peter A. Lio, M.D., explores the evidence for leaky gut and its relevance in dermatology while highlighting parallels with impaired skin barrier function in conditions such as atopic dermatitis.

Healthcare disparities exist in all fields of medicine, including dermatology. We seek to address these disparities in this article by outlining the differences in epidemiology, presentation, access and outcomes of five conditions in patients with skin of color.

In this article, Dr. Peter A. Lio discusses how recent advances in atopic dermatitis have led to a new standard of care, which aims to keep patients clear safely and maximize improvements in quality of life.

Some unconventional therapies for rosacea get to the root of the problem, with apparent positive impacts on inflammation, skin barrier dysfunction and vascular function.
