How do you remove flat warts?

I tend to have a lot of flat warts on my skin.

I had a laser procedure a few years ago to remove a lot of it as well.

Also, maybe because it has flared up a lot, it bothers me every time I look in the mirror.

If you have a lot of flat warts, your skin naturally looks messy.

I heard that if your immune system isn't good, it spreads more or appears in large numbers.

Because it is not easy to boost immunity in the short term

I think I should remove it...

How often do people who have it removed usually get the procedure done again?
