Dermal Therapy Fungistop 3-In-1 Nail Treatment is a self-care medical device for the treatment and prevention of Onychomycosis, a fungal nail infection. The formulation, with Olile-Active in combination with a bleaching agent (hydrogen peroxide) creates a hostile environment on the nail for the fungus causing the infection and removes unaesthetic discolouration of the nail resulting from fungal infection. After just one week of application, visible improvement can be seen on the infected nail area.
