Urea, also known as carbamide-containing cream, is used as a medication and applied to the skin to treat dryness and itching such as may occur in psoriasis, dermatitis, or ichthyosis. It may also be used to soften nails.
In adults side effects are generally few. It may occasionally cause skin irritation. Urea works in part by loosening dried skin. Preparations generally contain 5 to 50% urea.
Urea containing creams have been used since the 1940s. It is on the WHO Model List of Essential Medicines, the most effective and safe medicines needed in a health system. It is available over the counter. In the United Kingdom 100 g of 10% cream costs the NHS about 4.37 pounds.

Side effects
Common side effects of urea cream are:
- Mild skin irritation
- Temporary burning sensation
- Stinging sensation
- Itching
In severe cases, there can be an allergic reaction with symptoms such as skin rash, urticaria, difficulty breathing and swelling of the mouth, face, lips, or tongue.
Mechanism of action
Urea dissolves the intercellular matrix of the cells of the stratum corneum, promoting desquamation of scaly skin, eventually resulting in softening of hyperkeratotic areas. In nails, urea causes softening and eventually debridement of the nail plate.
