Mechanism of action

Urea acts as a keratolytic agent that breaks down and softens hardened, thickened skin by disrupting hydrogen bonds in keratin, while lactic acid provides gentle chemical exfoliation and humectant properties. Together, they improve skin barrier function, increase moisture retention, and promote removal of dead skin cells, making this combination effective for hyperkeratotic and xerotic skin conditions.
