How to remove flat warts on exposed areas

I have a question about flat warts.

Flat warts are depressed on exposed areas of the body.
I've heard that flat warts can increase in number, so I want to remove them safely as soon as possible.

I have some questions regarding how to remove flat warts at an ear clinic.
I'm curious about how Maypure removes flat warts.

Could you please let me know the method/approximate duration of the removal procedure?

I am curious about the level of pain during the removal procedure and whether anesthetic cream is used.
Could you also give me some guidance on post-procedure care methods or regenerative creams to use to reduce the risk of recurrence and minimize scarring?

I will visit the hospital to receive accurate treatment, but I would like to know the procedure and management process in advance.
Please reply. Thank you.
