“Urea? Isn’t that pee?” That was the first thing my mom said when she read the ingredients of the new cream I had just bought. Yes, it’s true: urea is linked to urine, but not the kind you’ll find in skincare products, obviously. In cosmetics, this substance is synthetically produced in a lab in a pure, safe, and controlled way, making it chemically identical to the natural one. Today, urea is considered one of the most effective allies against dry, rough, or stressed skin. It’s an often underrated ingredient, but one that can make a real difference. A true beauty secret that, I bet, will become yours too after reading this article!
What is urea really for? Benefits for the skin
Urea is primarily used to deeply hydrate the skin. At low concentrations, it works as a humectant: it helps the skin retain water and stay elastic. At higher concentrations, it also has a mild exfoliating effect: it removes dead skin cells and improves texture, without the need for harsh scrubs.

As mentioned before, the benefits of urea vary depending on its concentration in the product. When used in low concentrations (less than 5%), it primarily acts as a humectant: it draws in moisture and helps the skin hold onto it. This makes it a great ingredient for everyday face and body creams. It’s gentle and well-tolerated, even by those with sensitive skin or conditions like eczema or dermatitis, and it helps maintain a strong and healthy skin barrier. When urea is used at concentrations around 10–20%, it still hydrates the skin but also adds a mild exfoliating effect: it breaks down the bonds between dead skin cells, promoting renewal and leaving the skin smoother. It’s the right choice for rough or dark areas like knees, elbows, heels, or upper arms with those familiar little bumps typical of keratosis pilaris, improving the skin's texture over time.

In products with concentrations over 30%, urea acts as a true keratolytic agent, meaning it can break down and dissolve thickened layers of skin, typical of calluses and extremely dehydrated areas. Because it’s so potent, this formulation should be used carefully and is not suitable for the entire body. It can be irritating on thin or sensitive skin, so it’s best reserved for very specific areas and always used following medical advice.

Beyond hydrating and exfoliating, urea also has important soothing and repairing properties: it strengthens the skin barrier, prevents moisture loss, and protects the skin from irritants. It’s ideal for those dealing with eczema, psoriasis, or dermatitis, or with particularly sensitive skin. It’s also helpful for razor burn, red bumps, or irritation: it soothes, hydrates, and supports skin regeneration, leaving it soft and even.
