The active ingredient in corn remover pads, such as Dr. Scholl's Zino Soft Corn Pads, is salicylic acid, which can burn the skin or cause headaches, gastrointestinal distress, lightheadedness and allergic reaction, according to Everyday Health. People with kidney, liver or circulation disorders should avoid using corn remover pads or any other product made with salicylic acid unless instructed to by a doctor, as reported by Drugs.
The salicylic acid in corn remover pads causes layers of skin to peel away. This eliminates dermatological conditions like corns and warts, but it can also destroy healthy skin if applied incorrectly. Corn treatments are also available in gels and other topical agents.
