UREA

Urea (INCI: Urea) is a multifunctional cosmetic ingredient known for its ability to hydrate, exfoliate, and enhance skin barrier function. Naturally present in the skin’s Natural Moisturizing Factor (NMF), urea is synthetically produced for cosmetic use and is widely used in creams, lotions, and serums targeting dry, rough, or flaky skin.

Key Benefits:
Humectant Power: Draws moisture into the skin and retains it for long-lasting hydration

Keratolytic Action: Gently exfoliates dead skin cells and softens rough patches

Barrier Support: Improves skin resilience and reduces transepidermal water loss

Boosts Actives: Enhances penetration of other ingredients like niacinamide and AHAs

Soothing & Healing: Helps calm eczema, psoriasis, and keratosis pilaris

Common Applications:
Hydrating creams and body lotions

Foot balms and hand salves

Exfoliating serums and masks

Scalp treatments and hair conditioners

Sensitive skin formulas and baby care

Application Type Recommended Use Rate pH Stability Range
Leave-on skincare 3% – 10%  4.5 – 7.0
Rinse-off products 5% – 20%  4.5 – 7.5
Intensive treatments 20% – 40%  4.0 – 6.5

Formulation Tip: Urea is water-soluble and should be added during the cool-down phase (below 40°C) to prevent degradation. It pairs well with Glycerin, Panthenol, and Lactic Acid for enhanced hydration and exfoliation. For concentrations above 10%, urea acts as a keratolytic agent, making it ideal for rough skin areas like elbows, feet, and knees
