The main component of urea cream is urea. Urea is an organic molecule naturally produced when the body breaks down proteins. It also is made synthetically using ammonia and carbon dioxide.

Urea Cream Uses
Urea is one component of what’s known as natural moisturizing factor (NMF), a combination of substances that help keep the skin adequately hydrated. Urea helps bind water to rehydrate skin, improve skin barrier function, and regulate keratinocyte production.
Keratinocytes are the main cell types in the outermost layer of the skin, the epidermis, and play an important role in protecting skin integrity and maintaining skin structure. For this reason, urea cream helps treat dermatological conditions that cause the skin to become dry, flaky, or rough by rehydrating and strengthening the skin barrier.
Conditions that urea cream often helps treat include:
Eczema Atopic dermatitis Xerosis Ichthyosis vulgaris (dry skin with small scales) Psoriasis Hyperkeratosis (thickening of the outer layer of skin) Seborrhoeic dermatitis (skin condition of the scalp) Nail disorders Tinea pedis (athlete’s foot)
Side Effects
Urea cream is generally safe and has few side effects. However, some people may experience mild and temporary skin irritation in higher concentrations. This typically goes away on its own.
Contact your healthcare provider to rule out an allergic reaction if you have a more serious reaction, such as severe burning, itching, redness, or hives.
Dosage
Urea cream comes in concentrations ranging from 2% to 50%. Depending on your condition, low-dose or high-dose urea may be more appropriate.
Low-dose Urea
Low-dose (2% to 10%) urea cream is used primarily as a hydrating agent. This makes it best for treating xerosis; preventing and treating ichthyosis, atopic dermatitis, and psoriasis; preventing radiation-induced dermatitis; and maintaining healthy skin.
Medium-dose Urea
Medium-dose (10% to 30%) urea cream can be used as a hydrant, a keratolytic (an agent that helps break down skin flakes and scales), and a topical drug enhancer. These doses are also used to treat xerosis, ichthyosis, atopic dermatitis, and psoriasis and to maintain healthy skin.
High-dose Urea
High-dose (30% to 50%) urea cream is used as a keratolytic or a topical drug enhancer. In higher doses, urea is used to treat the following:
Localized hyperkeratosis (thickness of the skin) Psoriasis Keratoderma (thick epidermis) Calluses and corns Dandruff (flaky skin on the scalp) Nail disorders As a pretreatment for hyperkeratotic actinic keratoses (sun spots)
Precautions
Follow all instructions on the package’s instruction label when using urea cream. Do not use urea cream if you are allergic to it. Consult your healthcare provider before using urea cream on broken, inflamed, or burnt skin or if you are pregnant or breastfeeding. Discontinue use and contact your healthcare provider if you notice any extreme changes to your skin after using urea cream.
Interactions
There are no known interactions between urea cream and other medications. However, urea may increase the absorption of other compounds. So, talk to your healthcare provider if you are using other topical medications before using urea cream.
Summary
Urea cream is an over-the-counter topical medication used to treat various skin conditions by rehydrating and strengthening the skin barrier. Urea comes in doses ranging from 2% to 50%; different concentrations are used for different conditions.
Urea is generally safe and typically has few side effects or medication interactions. If you have questions about whether urea cream can help your skin condition, are unsure about dosages, or are worried about an allergic reaction, speak to your healthcare provider to determine what treatment is best for you.
A Word From Verywell
Urea cream can help treat skin disorders such as eczema, psoriasis, xerosis, and more. However, it may not work for everyone. If urea cream does not resolve your skin issues, don’t feel discouraged; other options can help you achieve healthy skin.
