Yes, some research indicates that urea-containing creams can contribute to skin lightening.
Based on a study using a specific urea-containing cream (referred to as cream foam A), clear skin lightening was observed in some patients.
How Urea Might Impact Skin Appearance
Urea is a common ingredient in skincare products, known primarily for its hydrating and exfoliating properties. While its primary roles are usually related to moisture retention and breaking down dead skin cells, the study highlights a potential effect on skin pigmentation.
The reference specifically notes:
On the other hand, the use of urea-containing cream A results in a clear lightening, in some patients even the complete disappearance of color shifts. Noticeable was the high degree of satisfaction and the tendency to continue to treat other age spots with cream foam A.
This suggests that in the context of certain formulations, like the cream foam A mentioned, urea may play a role in reducing the appearance of hyperpigmentation, such as age spots.
Key Observations from the Reference
- Clear Lightening: The cream led to a noticeable reduction in color.
- Disappearance of Color Shifts: In some cases, the pigmented areas completely disappeared.
- Patient Satisfaction: Users were highly satisfied with the results.
- Continued Use: Patients were inclined to keep using the product for other spots.
What This Means for Skin Lightening
While the exact mechanism by which urea might cause lightening isn't detailed in the provided reference, its known properties could contribute. Urea's exfoliating action helps remove dead skin cells, which can include pigmented cells, potentially leading to a brighter, more even skin tone over time. Its hydrating effect can also improve overall skin health and appearance.
It's important to note that this specific finding is linked to a particular formulation (cream foam A) containing urea, and results may vary depending on the product, concentration of urea, individual skin type, and the specific type of hyperpigmentation being treated.
Always consult with a dermatologist before using new products to address skin concerns, especially pigmentation issues.
