What is urea, exactly? Urea isn't just a metabolic byproduct—it's a valuable cosmetic ingredient and part of the skin's natural moisturizing factor (NMF).
What does urea do for skin? It helps hold onto moisture, keeping it soft and supple. In general, urea in skin care works in a few key ways: deep hydration, gentle exfoliation, and barrier repair.
Keep in mind that skincare products use a synthetic version of urea, which is odorless and safe.
The right concentration of urea for skin depends on your goals, where you're using it, and how strong you need it:
• 1-3%: Great for everyday hydration on the face and body. Helps maintain your skin's moisture balance and works well for daily use.
• 5-10%: Better for deeper hydration and softening dry, flaky skin. You'll often find this in hand and body creams.
• 10% and above: Talk to your doctor before trying this strength. When it comes to urea in skin care, most products stick to 10% or less.
Any skin type, but especially dry and dehydrated skin. Use with caution on sensitive skin, and avoid high concentrations.
Pairs well with almost any ingredient, especially panthenol, hyaluronic acid, ceramides, and others.
