Introduction
After applying a corn pad, removing the corn should follow safe and gentle principles to avoid damaging the surrounding skin. The process generally includes cleaning and disinfecting, allowing the hardened skin to soften, using specialized tools for assistance, gently peeling away dead tissue, and properly caring for and protecting the wound afterward. Before removing the corn, soak your feet in warm water for 10–15 minutes to soften the remaining calloused skin, then dry thoroughly with a clean towel.
After applying a corn plaster, removing the corn should follow the principles of safety and gentleness to avoid damaging surrounding skin. The process generally includes proper cleaning and disinfection, waiting for keratin softening, using specialized tools for assistance, gently peeling away necrotic tissue, and subsequent wound care. Detailed steps are as follows:
1. Clean and disinfect: Before removing the corn, soak the foot in warm water for 10–15 minutes to soften residual keratin. Dry thoroughly with a clean towel, then disinfect the corn area and hands with medical alcohol to reduce the risk of bacterial infection and create a clean environment for the procedure.
2. Wait for keratin to soften: Ensure the corn plaster has been used for sufficient time (usually 2–3 days), allowing the hard core of the corn and surrounding keratinized layer to fully soften. Proceed only when there is no obvious hardness upon pressing. Attempting removal before softening may cause skin damage.
3. Use dedicated tools: Choose a sterile comedone extractor or specialized keratin removal tool. Gently lift the softened edges of the corn using the blunt end of the tool, slowly peeling toward the center. Avoid excessive force; pause if resistance is encountered to prevent injury to healthy skin.
4. Gently remove necrotic tissue: Use the fingertip to gently grasp the softened edge of the corn and slowly lift upward, or lightly scrape away dead keratin with the tool. Do not attempt large-scale removal at once—gradually eliminate the hard core. Stop immediately if pain or bleeding occurs.
5. Post-removal wound care: After removing the corn, clean the wound with saline solution, apply an antibacterial ointment, and cover it with sterile gauze or a bandage to protect against contamination and friction. Avoid contact with dirty water and change the dressing daily until the wound is fully healed to prevent infection.
If after using the corn plaster the keratin remains insufficiently softened, significant pain occurs during removal, or signs of infection appear (such as redness, swelling, or pus discharge), discontinue self-treatment and seek professional medical help promptly. In daily life, wear loose and comfortable shoes and socks to avoid prolonged pressure on specific areas, helping prevent recurrence of corns.
