How does Excilor 2 in 1 Wart & Verruca Treatment work? Excilor Wart & Verruca Treatment 2 in 1 works by attacking the wart and verruca from the inside-out and from the outside-in. It is a self-Care medical device for an effective and fast acting treatment of common wart and foot wart. Excilor contains one product with a freezing agent, one product with a gel based on the Active Medical Ingredient TCA- Active combining cryotherapy and gel treatment in one device. By targeting the wart both rapidly freezing the core of the wart and peeling of the infected skin,, you combine the two most commonly used wart treatments for quicker results. Both the thickened skin of the wart and its causative virus are removed and new healthy skin will appear. What to Expect? During the treatment, a layer of callus (hardened skin layer) will be formed on the site of the treated wart. This callus will gradually wear. A blister, which may not be visible to the naked eye may appear underneath the wart. If this occurs, the thickened skin of the wart and its causative virus will disappear or fall of. To verify whether the wart has been removed you could soak the treated area in lukewarm water for 5 minutes and gently rub the callus carefully with a file. If the skin doesn’t show little black dots (little blood vessels, typical for a wart), the wart has been removed. The callus is not a wart. The callus may need a couple of weeks to wear before the optional result is seen. Renewed skin will appear smoother, slightly pink and regain its natural colour within subsequent weeks.
