Have so many brand products tested, as I do not want to let the wart cut off me. The Duofilm solution smells bestial but always let it dry a drop exactly on the center of the wart short and you can pull off a layer of skin hours later. And then again, the solution to bring (morning and evening). After only one week was my wart - I had almost two years - finally disappeared. Fantastic! Had I honestly do not think the happier I am. Conclusion: I can only recommend. The bottle looks so inconspicuous from but the best remedy for warts. THANKS
