When treating Filiform Wart, individuals must take enough care, especially when the treatment is directed towards cosmetically sensitive sites such as the face, and the neck. In treating Filiform Warts especially with Liquid Nitrogen, blisters on the face have said to be reported in some cases. This obviously is due to the softness of the skin in such sensitive parts of the body to liquid Nitrogen, forcing people to be very careful while treating Filiform Wart, which normally grows in the sensitive skin of the body.
