This problem is most commonly due to hand eczema (irritant or allergic dermatitis), where the skin becomes dry, thick, and cracked because of repeated exposure to water, soaps, detergents, or chemicals. Treatment focuses on protecting and repairing the skin: use a thick, fragrance-free moisturiser frequently (especially after washing hands), switch to mild soaps or cleansers, and avoid harsh chemicals or prolonged water exposure; wearing gloves while doing household work can help. During flare-ups, a doctor may prescribe a short course of a mild topical steroid or other medicated creams to reduce inflammation and heal cracks. It is important not to ignore recurring symptoms, as proper care can prevent worsening and infection, so consult a dermatologist if the problem persists or becomes painful.
