What Is Urea 40?

Urea, or carbamide, is a colorless, odorless solid that’s derived from animal or plant sources. It’s often used as a moisturizer in cosmetic products and as a treatment for dry, rough skin conditions like eczema and psoriasis.

Urea 40 as a Humectant

Humectants are compounds that help skin retain moisture. When used in skincare products, urea helps to keep the outer layer of skin hydrated and plump. This can prevent dryness, flakiness, and itchiness.

Urea as an Exfoliant

Urea 40 also has exfoliating properties. It helps to break down the bonds between dead skin cells, which can improve the appearance of rough, scaly skin.

Urea as an Antibacterial Agent

In addition to its moisturizing and exfoliating properties, urea also has antibacterial activity. This means it can help to kill bacteria that can cause infections.

Urea as a Keratolytic Agent

Urea is also a keratolytic agent, which means that it helps to break down dead skin cells. This can help to reduce the appearance of fine lines and wrinkles, as well as rough, dry skin. In addition, urea has antibacterial and antifungal properties, which can help to keep the skin clear and free from infection.
