Urea is a natural component of the skin, making up 7% of our natural moisturising factor (NMF) - essential for maintaining the health, function and hydration of the epidermis – which is produced synthetically for use in skincare. Known for its intense hydrating and gentle exfoliating properties, urea is the perfect skincare ingredient for dry, flaky sensitive skin, as well as skin prone to psoriasis and keratosis pilaris.
