Benefits of using Urea:
- Humectant: urea is a tiny molecule that penetrates through the top layer of the skin easily. Once it penetrates through the skin, it can hold onto water and prevent water loss.
- Keratolytic: urea at high concentrations can loosen the dead skin cells on top of the skin and can prevent unclogged pores. It is a gentler exfoliator that can also brighten the skin.
- Strengthening lipid barrier: Urea can also increase filaggrin, which is a vital protein, that plays an important role in the skin’s barrier function. It brings together proteins to the outermost layer of the skin to create a strong barrier.
- It protects against SLS: it reduces the skin’s susceptibility to sodium lauryl sulfate (SLS).
- Helps with different skin diseases: It helps treat ichthyosis, xerosis, psoriasis, seborrheic dermatitis, atopic dermatitis, contact dermatitis, radiation-induced dermatitis, onychomycosis (a.k.a nail fungus), tinea pedis, keratosis, and pruritus.
Urea is used in prescriptions and OTC products to increase the penetration of active ingredients. It does this by removing the dead skin cells on the top of the skin and allowing the actives to pass through.
