Urea Cream
Strength Differences and How to Choose a Body Lotion

What urea cream does for skin, and why

Urea is a moisturizer your skin already makes. It is one of the natural moisturizing factors (NMF) that hold water in the outer skin layer, so a urea cream tops up what dry skin has run short of.

• Moisture: it attracts and holds water, so a dried-out outer layer fills back up. That is why tight, flaky skin softens.
• Smoothing rough skin: at higher amounts it loosens thick, hardened skin. It is known to do this by weakening the bonds that hold built-up skin cells together, which is why it is a favorite for heels and elbows.
• Barrier: research has also described benefits for the skin barrier beyond plain moisture (Piquero-Casals et al., 2021).

It is not a common moisturizer, so you have to look for it. Of the 2,426 full ingredient lists we have collected, only 36 contain urea.

Urea strength: the difference between moisturizing and exfoliating

Urea does different work depending on how much is in it. A review of urea in skin care puts the line at 10%: at or below that it acts as a moisturizer, and above it it starts to dissolve dead skin (Celleno, 2018).

For dry skin on the whole body or the face, 10% or less is enough. For thick, built-up skin such as heels, pick a higher strength. Most everyday moisturizing creams contain only a little urea for moisture, so if you want exfoliation, check the strength on purpose.

Which skin suits urea cream

Dry skin that flakes and feels tight suits it well. If your shins turn white every winter or your heels crack, urea is the first ingredient to consider.

Skin that is very sensitive, or cracked and broken, may feel a sting. A review of 81 clinical publications named mild irritation as the most common adverse effect and found no systemic toxicity (Pan et al., 2013). A later review noted these reactions grow more frequent at higher strengths (Piquero-Casals et al., 2021). If you are new to it, start with a small area and a low strength. People with a skin condition such as atopic dermatitis should ask a dermatologist first.

How to choose a urea body lotion

A lotion spreads more easily than a cream when you cover the whole body. Check these three things.

• Stated strength: in Korea, a product that puts urea in its name must also state the urea content on the package (Enforcement Rule of the Cosmetics Act, Article 19). Use 10% as the line between moisturizing and exfoliating.
• Other moisturizers alongside: products rarely rely on urea alone. All 36 of the products we collected also had glycerin, and many paired it with hyaluronic acid or panthenol.
• Ingredients that seal water in: if your skin is very dry, look for an oil or a ceramide that keeps water from escaping. Few of the urea products also carried ceramide.

Thick, rough areas such as heels stay coated longer with a cream than with a lotion. Lotion for the body and cream for the spots that crack is one way to split it.

Urea cream and lotion products

Fewer products carry a generous amount of urea than you might expect. We picked the ones with a clear use.

• Holyritual Relaxed Foot Treatment Cream is a foot cream with a generous amount of urea. It is the first to look at if rough heels are the problem.
• Clinique Dramatically Different Moisturizing Lotion carries more urea than most face lotions. It is an easy start if you want to try urea for facial moisture.
• From Lier EGF Sebum Pack Hyper Active Pore Sebum Mask also contains a fair amount of urea, but as a pore mask it serves a different purpose from a moisturizing cream.

Primera Alpine Berry Watery Cream, The History of Whoo Jinyulhyang Anti-Wrinkle Enriching Cream and The Ordinary Rice Lipids + Ectoin Microemulsion use urea as a supporting moisturizer. They suit overall moisture rather than smoothing rough skin. For a product not in our list, enter its name and we will analyze the ingredients.

How to apply urea cream and what to watch

• When: apply while skin is still damp after washing. It locks the water in better.
• First use: test a small patch, such as the inner arm, and watch the reaction.
• Where to avoid: skip cracked, bleeding or inflamed skin and the area around the eyes.
• Other actives: stacking it with exfoliating acids on the same day can pile up irritation. Add one at a time.

Frequently asked questions

Can I use urea cream every day?

If the goal is moisture, daily use is fine. Pace a higher-strength exfoliating product by how your skin reacts. If it stings or turns red, take a break and switch to a lower strength.

Is it okay to use urea cream on my face?

Facial skin is thinner than skin on the body and reacts more easily. Start with a low-strength product made for the face and keep it away from the eye area. Moving a high-strength heel cream to the face is not recommended.

Are urea and carbamide the same ingredient?

Yes. Carbamide is another name for urea, and ingredient lists almost always print it as urea.

What side effects does urea have?

In reviews of the clinical literature the most common adverse effect was mild irritation, and it was more frequent at higher strengths. Skip cracked, broken or inflamed skin because it can sting there.
