It’s burning the warts, but you have to apply very often. The feeling is not the best but still better than in the Hospital.the wart becames white in one minute, after that the burning feeling comes its last maximum 5 minutes.
The seller shipped the item quickly. It came damaged and that's why it leaked on its way to me. So no seller's fault. Seller is good, returned my money. Just that ask the seller to pack the item well next time.
