Hand dermatitis can be mild to severe and is often mistaken for dry skin until its relentless symptoms become unmistakable. Defined by red, itchy, dry, cracking, or blistering palms and fingers, it may even bleed, crust, or pain deeply in chronic cases. Some people experience thickened, leathery skin or leathery patches that evolve over time, signaling a deeper barrier dysfunction rather than temporary drought. Healthcare professionals and authoritative sources underscore that effective management must target both inflammation and skin barrier reinforcement. Diagnosis typically starts with a clinical evaluation of the hands’ physical condition, a review of history, and, if needed, patch testing. In certain complex cases, a skin biopsy can clarify the underlying type of hand eczema .

Causes and triggers of hand dermatitis are multifactorial and warrant a detailed understanding to guide both individuals and clinicians toward smarter prevention. Irritant contact dermatitis arises when daily exposure to harsh agents—such as cleaning chemicals, detergents, solvents, prolonged or repeated water contact, friction, or temperature extremes—break down the skin’s natural oils and compromise barrier integrity . Allergic contact dermatitis, on the other hand, stems from immune reactions to specific allergens like nickel in jewelry, latex in gloves, or common fragrances and preservatives in soaps, lotions, and detergents. Plants and industrial agents may also trigger responses in sensitized individuals . Occupational exposures—such as frequent hand washing in healthcare, chemical and construction work—dramatically amplify the risk of hand eczema .
