How does Wart remover work?

Wart removers typically contain active ingredients like salicylic acid or freezing agents (such as liquid nitrogen). Salicylic acid works by softening and peeling away the layers of skin that make up the wart, gradually eliminating it over time. Freezing agents destroy the wart tissue by freezing it, causing the wart to fall off. Both methods stimulate the immune response to help prevent the wart from returning.
