Loceryl fungal nail lacquer is specially formulated to treat fungal nail infections. The active ingredient amorolfine penetrates the cell membrane and weakens it. This causes the main components of the infection to leave the cell. Eventually, the infection dies and the treatment continues to provide further protection from infections. Loceryl lacquer effectively treats fungal nail infections because it is soup and water resistant. This protection results in the medication being able to settle in the nail bed without being washed away. Apply the treatment is simple using the special applicator cap. Loceryl should be applied to the affected area once or twice a week.
