What is Urea?

A natural moisturizing factor (NMF) that softens keratin and attracts moisture

At 5% or less it provides hydration; at 10% or more it has keratolytic effects. Effective for xerosis and keratosis.

Key properties & actions

Urea is a component of the skin's natural moisturizing factors (NMF), and is known to work by drawing in moisture and loosening the bonds within the stratum corneum. Its action is described as varying with concentration—lower concentrations are more oriented toward moisturization, while higher concentrations lean toward softening and loosening thickened keratin. It is frequently associated with dry, thickened skin conditions.

How to manage

Products with a lower concentration of around 5% are generally suitable for whole-body moisturizing use, while concentrations of 10% or higher are typically recommended for targeted application on rough, thickened areas. Application to wounded or irritated skin should be avoided, and if stinging or redness persists, reducing use and consulting a dermatologist is recommended.

Good to know alongside

It is frequently mentioned alongside moisturizing and exfoliating ingredients such as glycerin, lactic acid, and salicylic acid in foot care and body products. It is referenced in the management of skin with pronounced dry keratosis.

Everyday care tips

For thick, rough areas like the heels, applying the product while there is still a little moisture left after bathing and then occluding it can enhance the perceived moisturizing effect.
