The short explanation
Dry, itchy skin on the legs is very common in older adults, especially in winter. As we age, the skin makes less oil and holds less moisture, so it dries and cracks easily, a condition sometimes called winter itch or asteatotic eczema. Scratching damages the skin further, which can lead to bleeding and infection. Helpful steps at home include using lukewarm rather than hot water for bathing, using a mild soap or soap-free cleanser, patting the skin dry, and applying a thick, fragrance-free moisturiser right after bathing while the skin is still slightly damp. Keeping her nails short reduces damage from scratching. If the itching is severe, the skin is broken, or it does not improve, a doctor can suggest a suitable treatment.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Some health conditions can cause itching in older adults, including diabetes, thyroid problems, kidney and liver disease, and iron deficiency, so a doctor may suggest blood tests.
- Some medicines can also cause dry or itchy skin; bring her medicine list to the appointment.
- Avoid applying strong home remedies, kerosene or harsh antiseptics to broken skin.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what is causing her itching. A doctor needs to examine her skin and may order tests.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this dry skin eczema or something else?
- Should she have blood tests for other causes of itching?
- Which moisturiser and treatment would suit her?
- Could any of her medicines be causing this?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a doctor within a few days if the skin is red, hot, swollen, oozing pus, or she develops fever.
Raise it at a routine appointment
- Book a routine appointment if itching continues despite moisturising, or disturbs her sleep.
