Removal of flat warts and genital warts

As I get older, I notice flat warts appearing on my face, and I can also see a mole on my neck.

If you want to remove everything, it's not just about the cost but also the number of items. In such cases, is it better to remove everything at once even if it's difficult? Can I divide the areas and do it separately?

And after laser treatment, how long should I keep a bandage like a duoderm on for protection?

I want to remove everything, but considering the significant increase in the number of flat warts, I think it will take quite a while for the skin to recover, and it might be uncomfortable in daily life, which worries me.
