Apply in a thin layer over the entire infected nail surface and 5mm of surrounding skin and if possible under the free edge of the nail. Allow to dry for approximately 30 seconds. The treated nail should not be washed for at least 6 hours, therefore, application in the evening before going to bed is recommended. Apply RejuveNail Anti-fungal Nail Lacquer on the infected nails once daily or as otherwise directed by your doctor or pharmacist. It should be left on the nail for at least 6 hours. In case of unintentional removal by washing, it can be reapplied
