The ingredient narratives reshaping clean beauty.
Urea
aka carbamide
The Eucerin and Aquaphor staple having a clean-aware renaissance via Inkey List Urea Cream and the German-derm-influenced minimalist routines that took TikTok in 2024–2025. Urea is the only ingredient that swings from humectant (≤10%) to keratolytic (≥10%) on the same label — a pharmacological dual-personality that solves both dryness and KP / heel callus / hyperkeratosis with one molecule. Naturally a component of NMF.
- humectant at low doses — restores stratum corneum hydration
- keratolytic at high doses — dissolves KP, callus, and hyperkeratotic patches
- amplifies penetration of co-formulated actives
- KP and body smoothing creams
- heel and elbow treatments
- face hydration creams (CeraVe SA, Eucerin Urea Repair)
Body: 10–40% for KP and callus; face: 2–10% for hydration. pH-sensitive — alkaline conditions cause hydrolysis to ammonia (off-smell, irritation); urea formulations need acidic buffering. Pairs with lactic acid for body, ceramides for face.
High-dose urea (>20%) stings broken or eczema-active skin; low-dose is fine. Confused with 'urine' in marketing folklore — modern urea is synthesized.
Trusted, with clean-clinical crossover momentum.
