Use

Urea is incorporated into cosmetics for a variety of purposes, including moisturizing, desquamating, anti-microbial, and buffering. urea is regarded as a “true” moisturizer rather than a humectant because it attracts and retains moisture in the corneum layer. It facilitates the natural exfoliation of keratinocytes given its ability to dissolve intercellular cement in the corneum layer. Through its anti-microbial properties that inhibit the growth of micro-organisms in a product, urea can also be part of a larger preservative system. This ingredient’s buffering action is attributed to its ability to regulate the hydrolipid mantle. In addition, urea is found to enhance the penetration and absorption of other active ingredients, relieve itchiness, and help leave the skin feeling soft and supple. Anti-inflammatory, anti-septic, and deodorizing actions allow it to protect the skin’s surface against negative changes and help maintain healthy skin.
