How could i get rid of a verruca without scarring?

Size?: It depends upon the size. Larger ones tend to leave some scarring. A surgeon can remove them with the least scarring at times depending upon size and location.

Several treatments.: You can try over the counter wart removers, but be careful: i've seen them do more harm than good. Other options your doctor might offer include cryotherapy (freezing the wart), electrocautery (burning the wart), laser treatment, or several different topical chemical treatments. If the treatment is typically uncomfortable, your doctor can numb the area before proceeding.
