Ingredients Details
Urea
Common Name(s): Urea,nmf component keratolytic,dual humectant+exfoliant
CAS Number: N/a
DESCRIPTION
What It Does: At 2โ10%: provides deep humectancy, softens sc, and improves other active penetration. at 10โ40%: keratolytically dissolves corneocyte protein bonds for intensive exfoliation of hyperkeratotic skin (calluses, eczema plaques, psoriasis).
Why It's Used: Urea combines two otherwise separate ingredient classes (humectant and keratolytic) in one molecule, with formulator-controlled function through concentration selection โ uniquely versatile for multiple skin condition applications.
How It Works: Urea's carbonyl and amine groups form h-bonds with water (humectancy) and with corneocyte keratin (penetration). at high concentrations, urea disrupts keratin hydrogen bonds (chaotropic activity) solubilising the sc protein matrix โ concentration determines whether humectant or keratolytic effect predominates.

SCIENTIFIC NOTE
Urea is the most concentrated natural nmf component โ healthy sc contains 28 mg/g urea versus 2 mg/g in xerotic (dry) skin. topical urea application directly replenishes the physiological nmf deficit that drives dry skin conditions.
