Verrucas on the way out?

[Ewanthescreamsheep]

We've been treating dd's verrucas and the surface went dry and brown, and peeled off like a scab.
The skin looks pink underneath.
Are these on the way out now? Would you just leave alone a while?
I'm concerned more small ones may be beewing around the edges, as they have been gradually spreading outwards from the initial one over the last few months, but don't want to risk treating unnecessarily.

They look like they're on the way out to me. When they got to that stage (with bazuka) I left them a few days and checked they didnt get any bigger. Now all gone thnkfully.
