Urea

Definition

Urea is a naturally occurring compound that is also produced synthetically for use in cosmetics and skincare. It is a highly effective humectant and skin-conditioning ingredient that helps attract and retain moisture while gently softening rough, dry skin.

In skincare, urea is valued for its dual ability to hydrate the skin and, at higher concentrations, gently exfoliate dead skin cells, making it a popular ingredient in products for dry, rough, and flaky skin.

INCI Name: Urea

History

Urea was first identified in human urine in the 18th century and became the first organic compound successfully synthesized in a laboratory in 1828 by German chemist Friedrich Wöhler. This breakthrough helped establish the field of modern organic chemistry.

Today, cosmetic-grade urea is synthetically manufactured and does not come from human or animal urine.

Source

Although urea occurs naturally in the skin as part of the Natural Moisturizing Factor (NMF), the urea used in cosmetics is produced synthetically under strict quality standards.

Synthetic cosmetic-grade urea is:

  • Highly purified

  • Vegan-friendly

  • Free from animal-derived ingredients

  • Safe for cosmetic use when formulated appropriately

Cosmetic Uses

Urea is commonly found in:

  • Facial moisturizers

  • Body lotions

  • Hand creams

  • Foot creams

  • Heel repair creams

  • Dry skin treatments

  • Keratosis pilaris products

  • Psoriasis-support skincare

  • Eczema-support moisturizers

  • Overnight masks

  • Intensive moisturizing creams

Skin Benefits

Urea helps:

  • Deeply hydrate the skin

  • Strengthen the skin barrier

  • Reduce moisture loss

  • Soften rough, dry patches

  • Improve skin smoothness

  • Gently exfoliate dead skin cells at higher concentrations

  • Enhance the absorption of certain skincare ingredients

  • Relieve tight, flaky skin

  • Improve the appearance of cracked heels and elbows

Texture

Urea contributes to products that feel:

  • Lightweight

  • Smooth

  • Non-greasy

  • Fast absorbing

  • Softening

  • Comfortable on dry skin

The overall texture depends on the complete formulation.

Stability

Urea is generally stable in properly formulated cosmetic products.

For best stability:

  • Store in a cool, dry place.

  • Keep containers tightly sealed.

  • Avoid prolonged exposure to excessive heat.

  • Follow the manufacturer's expiration or period-after-opening (PAO) guidance.

Formulators carefully control pH and ingredient compatibility to maintain product performance.

Urea Concentrations in Skincare

Different concentrations of urea serve different purposes:

  • 2–5%: Lightweight hydration for everyday facial and body moisturizers.

  • 5–10%: Enhanced moisturization and softening for dry or rough skin.

  • 10–20%: Helps soften thickened skin and provides gentle exfoliation.

  • 20–40%: Primarily used in specialized products for very thick, rough skin such as calluses or severely cracked heels. These higher concentrations are generally not intended for routine facial use.

Frequently Asked Questions

Is cosmetic urea made from urine?

No. Modern cosmetic urea is produced synthetically in laboratories and is not derived from human or animal urine.

Is urea safe for sensitive skin?

At lower concentrations, urea is generally well tolerated by many people with dry or sensitive skin. Individuals with very sensitive or compromised skin should patch test new products before regular use.

Is urea vegan?

Yes. Cosmetic-grade synthetic urea is considered vegan because it is manufactured without animal-derived ingredients.

Does urea exfoliate the skin?

Yes. At higher concentrations, urea has keratolytic properties, meaning it helps loosen and remove dead skin cells while continuing to provide hydration.

Is urea good for acne-prone skin?

Urea itself is generally considered non-comedogenic and helps support the skin's moisture barrier. Whether a product is suitable for acne-prone skin depends on the entire formulation, not just the presence of urea.
