Common causes and triggers
Scaling can arise from many sources. Frequent causes include dry skin, sunburn, chronic dermatologic conditions such as atopic dermatitis, seborrheic dermatitis or psoriasis, fungal or bacterial infections, irritant or allergic contact reactions, and environmental factors like cold, wind or low humidity. Repeated hot-water exposure or some cosmetic products may worsen peeling. Systemic issues or nutritional shortfalls can also change skin texture.
