Will using Wartner Verruca & Wart Removal Pen hurt?

TCA is a corrosive agent and causes skin peeling within 10-15 minutes. Large amount of TCA gel might cause a slight tingling sensation that should disappear quickly. If applied on the thin, damaged or sensitive skin, TCA may cause burning or a painful sensation – but the sensation is transient and should disappear within few minutes. If painful sensation persists the excess of the gel should be immediately cleaned out with water.
