Urea-containing cream
(Redirected from Keralac lotion)
Overview[edit | edit source]
Urea-containing creams are topical formulations used in dermatology to treat a variety of skin conditions. Urea, a naturally occurring compound in the body, is known for its keratolytic, hydrating, and exfoliating properties. These creams are commonly used to manage dry skin, eczema, psoriasis, and other conditions characterized by hyperkeratosis.
Composition[edit | edit source]
Urea creams typically contain urea concentrations ranging from 5% to 40%. The concentration of urea determines the cream's specific use and effectiveness. Lower concentrations (around 5-10%) are primarily used for their moisturizing properties, while higher concentrations (20-40%) are used for their keratolytic effects.
Mechanism of Action[edit | edit source]
Urea acts as a humectant, drawing moisture into the skin and enhancing its hydration. It also has keratolytic properties, meaning it helps to break down the keratin in the outer layer of the skin, promoting exfoliation and improving skin texture. This dual action makes urea an effective treatment for conditions involving dry, rough, or scaly skin.
Uses[edit | edit source]
Urea-containing creams are used in the treatment of:
- Xerosis: Urea helps to restore moisture to dry skin.
- Psoriasis: The keratolytic action of urea aids in the removal of scales.
- Eczema: Urea creams can help to alleviate the dryness and itching associated with eczema.
- Ichthyosis: Urea softens and smooths the thickened skin characteristic of this condition.
Application[edit | edit source]
Urea creams are typically applied to the affected area once or twice daily. It is important to follow the specific instructions provided by a healthcare professional or the product's labeling. Overuse or application to sensitive areas can lead to irritation.
Side Effects[edit | edit source]
While generally well-tolerated, urea creams can cause side effects in some individuals. These may include mild skin irritation, redness, or a burning sensation. If severe irritation occurs, use should be discontinued, and a healthcare provider should be consulted.
