I have a wart on my finger and I put on the compound w like it said every day for a week or 2. Now it's like white and smooth not a cauliflower. When do I have to stop applying the cream?

Think onion. A wart is a multilayered collection of the germ in your tissue. The compound W acts as a toxic agent that kills a layer of wart at a time. You brush off the dead cells & do it over & over until you are below skin level and see raw flesh. If you stop too soon, it re-emerges within weeks/months. It is like an iceberg with a part above & a part below skin level.
Peel off. You can lightly peel off wart with ped egg to flat surface. If there is wart left or it starts to regrow restart medicne.
