Urea, also known as carbamide, is an organic compound with chemical formula CO(NH2)2.
Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, highly soluble in water, and practically non-toxic. Urea is widely used in fertilizers as a source of nitrogen (N) and is an important raw material for the chemical industry.
The 40% of Urea contained in the plaster acts by modifying the pH of the area subject to treatment, weakening the part of the diseased nail with the consequent selective detachment of such part and facilitating its cutting and, therefore, its removal. After applying the plaster containing the disc with urea, an improvement in the nail status can be noticed, thanks to the physical mechanism featured by the product, which, acting on the pH of the environment, creates the optimal conditions to prevent the development of the fungus. Therefore, the defect will stop and the nail will grow back healthy moving forward the damaged part that has to be progressively eliminated with the regular nail cut. It is essential to start the treatment right when the first signs of mycosis are detected, in order to obtain more rapid and effective results.
