Urea cream for feet: what it does and how to use it

What does urea cream do for your feet?

Urea works in two ways. As a humectant, it attracts and holds water in the outer skin layer. As a keratolytic, it softens thick surface skin so that dead skin can come away more easily. Those actions make urea useful for dry, rough heels and areas of thickened skin, including calluses. Most cracked heels start with dryness, while pressure and friction can contribute to thickening. Cracks also weaken the skin's protective barrier and can allow infection to develop.345

Which strength should you choose?

For dry, thickened heel skin, 10% is a reasonable starting point within the usual heel care range. Choose the strength for the problem rather than automatically buying the highest percentage. Higher concentrations can cause more irritation. Some strong preparations are intended for thickened areas or nail treatment, so check the intended use as well as the number on the tube. Once the thickening improves, switch to a standard moisturizer, or a 5% urea preparation if continued skin softening is needed.36

Can you put urea on cracked heels?

Urea can be part of care for dry, cracked heels, but do not put it directly into broken or bleeding skin. Apply it to the surrounding intact, dry skin instead. Avoid infected or oozing areas and skin with severe, widespread redness. A deep, painful or bleeding crack needs a different approach from rough surface skin. Severe cracks, or heels that do not improve with home care, need assessment by a dermatologist.47

How do you use urea cream on your feet?

1. 1Wash gently with lukewarm water and a fragrance free cleanser. Keep baths and showers to 5 to 10 minutes; prolonged soaking can worsen dryness.
2. 2Blot your feet gently with a towel. Dry carefully between your toes, while leaving the intact heel skin slightly damp.
3. 3Apply a thin film of urea cream to the dry, thickened areas within five minutes of bathing. Avoid eyes, lips and other sensitive areas, and follow the label's application frequency.
4. 4At bedtime, apply plain petroleum jelly over the heel moisturizer to help retain moisture.
5. 5Put on cotton socks to hold moisture around your feet overnight. Repeat the heel care routine daily while the dryness improves.

Socks also help keep petroleum jelly off your bedding, which has not volunteered for a foot treatment.7

Urea cream can be applied after bathing during the day; bedtime is useful for the petroleum jelly and sock layer. There is no single application frequency for every strength and formula, so use the directions on your own product. For prescribed urea, do not double an application to make up for a missed one.1

How long does it take to work?

Allow about two weeks of regular use to see a response from an over the counter exfoliating heel treatment. Look for less roughness and softer skin rather than expecting thickened skin to disappear after one application. That timeframe is not a deadline for a deep crack to heal. If the cracks keep returning or fail to improve, seek an assessment rather than repeatedly increasing the strength.5

What should you pair it with?

Petroleum jelly helps seal in moisture, while a cream containing ceramides helps support the skin barrier. Foot files and pumice stones should be used only as directed and in moderation, never over inflamed, itchy or sensitive areas. Avoid foot peels if you have broken skin or a skin condition such as eczema, psoriasis or athlete's foot. If you use prescription treatment on the same area, discuss the combination first: urea can increase the penetration of medicines such as corticosteroids.45

Continue moisturizing after your heels recover, and wear shoes that fit properly rather than worn shoes or styles that leave the heel exposed. A moisturizer belongs in foot care even when sandal season is not running the marketing department.57

Who should be careful, and when should you stop?

Urea preparations are usually well tolerated, but mild stinging, itching or redness can occur. Stop and get advice for burning, crusting, peeling, or a persistent, bothersome reaction. Hives or swelling of the face, lips, tongue or throat need urgent medical attention. Before using medicinal urea preparations, tell your clinician if you are pregnant, trying to conceive or breastfeeding, or have an allergy to urea or another ingredient. Ask about use in children rather than applying an adult foot treatment by default.14

If you have diabetes, check your feet every day, including the soles and between the toes. Dryness can lead to deep cracks and serious infection, and wounds can heal slowly. Have a dermatologist or podiatrist treat corns and calluses rather than removing them yourself. Seek immediate care for swelling and discoloration, tenderness, pain, pus or other fluid, or a wound that worsens or fails to heal.2

What does urea cream do for your skin?

Urea is naturally present in the outer skin layer and helps maintain hydration. Urea creams use synthetically manufactured urea to increase water retention, reduce water loss and soften the surface. Lower concentrations support moisture maintenance; stronger preparations have a greater role in loosening thickened skin. Urea is also used in care for dry, scaly conditions such as eczema and psoriasis, with the strength and formulation chosen for the condition.46

Can you use urea cream on your face?

Use caution with urea on the face, and keep it away from the eyes, lips and sensitive areas. Do not automatically repurpose a strong heel cream as a facial moisturizer. The strength and formulation need to suit the area being treated, so a shared ingredient does not give a foot cream a promotion to every shelf in the bathroom.14
