I had plane wart on the face before, it begun at just one small spot and it speads to 134 spots after a year before i consult the doctor. The color of plain wart is very pale and not very visible, so this disease is easily ignored.
I consulted the dermis doctor and had the laser treatment last month (HK$7000). There were burnt scars right after the treatment, and it will disappear after few days. There is no scare left now. This is the quick and effective way to cure wart. Because wart is virus and have to removed from depth of derm, otherwise it will happen again.
Just a reminder, you can claim the surgury fee if you have the hosp insurance.
