The main treatment modalities for corns include the use of corrosive medications, physical therapy and surgical excision, etc. Windex has no therapeutic effect on corns. 1. Corns are mainly caused by friction and pressure resulting in limited keratosis, which can cause pain when walking or standing. The main treatments include applying corrosive drugs such as 10%~15% salicylic acid ointment to make it soften and fall off, or physical treatments such as laser, electrocautery, etc. to remove the surface skin tissues, and surgical excision can be carried out if necessary. 2. Windex has a cooling effect to relieve the itch, but can not eliminate corns caused by corns, so there is no treatment for corns. It is recommended that patients with corns go to the hospital, under the guidance of a professional doctor to choose the appropriate treatment, do not blindly use their own medication.
