20 Nov 2023 --- A recent study focusing on the epidermis helps explain the activities of hemoglobin alpha (HBA) in this outermost layer of the skin. While this protein is typically found in red blood cells — actively delivering oxygen to cells and tissues throughout the body — findings from the paper uncover its protective functions in the skin barrier. Underscoring the complexity of skin biology, the discovery points to potential new pathways to formulating dermatological solutions aimed at fortifying the skin’s natural defenses.
