Dry skin, or xerosis, is a condition characterised by a lack of moisture in the outer layer of the skin, leading to scaling, itching, and cracking. It is clinically significant as it can predispose individuals to infections, exacerbate dermatological conditions like eczema, and impact overall skin barrier function. A common association is with environmental factors such as low humidity or excessive bathing, which can worsen the condition and complicate patient management.
