If you’ve struggled with dry, flaky skin that regular moisturizers just won’t fix, urea may be the ingredient that turns it around. It’s one of the most well-researched skincare actives for dryness—and one of the least understood.
See what it actually is, how it works, and why focus on the label matters more than most people realize.
What is urea in skin care?
Urea is a natural compound that your skin already produces as part of the Natural Moisturizing Factor (NMF) – the system that keeps the skin barrier hydrated from within.
When the skin is very dry, its natural urea levels drop. Applying it topically replenishes what’s depleted, but it does more than just add moisture back.

Urea is what is called a keratolytic – Softens and breaks up hardened, thickened skin. This is what makes it so different from standard moisturizers. Regular lotions sit on top of the skin and prevent moisture loss. Urea actively penetrates the outer layer of the skin and moisturizes from within, while also loosening the bonds between dead skin cells so they can be shed naturally.
What does urea actually do?
Depending on the concentration, urea does different things:
At low concentrations (2–10%):
- It acts mainly as a humectant – it draws water into the skin
- Softens rough, dry skin
- Improves the skin’s ability to retain moisture
- Suitable for generally dry skin, mild peeling and daily maintenance
In moderate concentrations (10–20%):
- Adds keratolytic action – begins to dissolve thickened skin cells
- Treats keratosis pilaris (chicken skin bumps)
- Helps with rough elbows, knees and very dry feet
- Useful for persistent dryness that normal lotions have not resolved

At higher concentrations (20-30%+):
- Strong keratolytic effect
- Specially designed for cracked heels, severely thickened skin
- Not suitable for the whole body – targeted use in difficult areas
This is why the percentage on the label is not a marketing number. It defines what the product will actually do.
Why do regular moisturizers not work for very dry skin?
Typical body lotions are mostly emollients and occlusives – smooth the skin and seal the surface to slow down moisture loss. This works well for mild dryness.
But very dry skin has a deeper problem. The skin barrier itself is at risk. Moisture escapes faster than it can be replaced. The outer layer of the skin thickens and hardens, which prevents absorption.
Urea solves both problems at once—it softens the thick outer layer so ingredients can penetrate, and it draws and holds water into the skin instead of just sealing the surface.
Who benefits most from urea?
- Women with dry skin that feels rough or scaly, especially on the feet and hands
- Anyone dealing with cracked heels that haven’t responded to standard creams
- Those with keratosis pilaris (abnormal skin on hands and feet)
- Anyone who has dry skin again within a few hours of applying the lotion
- Postpartum skin changes – hormonal dryness often responds well to urea
How to choose the right rate of urea
- Mild to moderately dry skin on the body → Lotion 10% urea for daily use
- Very dry, flaky skin or rough patches on the feet and hands → 20% urea lotion
- Severely cracked or dense heels → 20–30% urea in targeted foot form
For very dry and flaky skin, 10% and 20% urea-based lotions are the two most practically useful concentrations. Be Bodywise offers both – the 10% Urea Body Lotion for generally dry skin and the 20% Urea Lotion for very dry and flaky skin – both rated 4.6 on the website, dermatologist formulated and paraben free. Especially for cracked heels, the 20% and 30% Urea Foot Roll-Ons are designed for targeted application. Compare concentration with severity of dryness before choosing.
How to use urea lotion correctly
- Apply immediately after bathing, on slightly damp skin – this maximizes moisture absorption
- For heels, apply before bed and cover with socks overnight for best results
- Start with a lower concentration and only go up if needed
- If you feel tingling on broken or very inflamed skin, reduce the frequency of application
FAQ
Q: Is urea safe for daily use?
Yes – at concentrations of 10–20%, urea is safe for daily use in the body. It appears naturally and is well tolerated by most skin types.
Q: Will urea lotion make my skin peel?
At 10%, it’s unlikely. At 20%+, you may notice some mild shedding of dead skin in the first few days – this is the keratolytic action working properly. It settles with consistent use.
Q: Can I use urea on my face?
Lower concentrations (2–5%) are used in facial products. The higher concentrations designed for use on the body are not suitable for facial skin, which is more sensitive.
Q: Is urea appropriate during pregnancy?
Urea is generally considered safe during pregnancy when used topically, but always consult your doctor for specific advice.
Q: How long before I see results?
For softness and hydration, many women notice a difference within the first week. For thick or cracked heels, 3-4 weeks of continuous use is a more realistic schedule.
Q: Can I use urea with salicylic acid?
Yes – they complement each other. Urea hydrates and softens, salicylic acid exfoliates pore-level build-up. On alternating days or in different areas, they work well together.
