The Miranel Antifungal Treatment formula uniquely combines a smooth and refreshing combination of natural tea tree oil, menthol, eucalyptus and camphor with an innovative technology to allow the pharmaceutical grade Miconazole Nitrate to penetrate the affected area. Simply put, rather than treating the fungus on the surface, Miranel's penetration enhancement properties help the antifungal treatment reach the area where fungus lives on the skin, around and under the nail.
