Methods of removing corns on feet include topical medication, surgical treatment, physical therapy and so on. Corns occur in adults, mostly in women, mainly due to the thickening of the stratum corneum induced by long-term pressure and friction. 1. Topical drug treatment: For smaller corns, you can usually use salicylic acid phenol cream to corrode the lesions and make them fall off under the guidance of a doctor. But pay attention to the use of drugs to avoid damage to the surrounding normal tissue. 2. Surgery: When the effect of external drug treatment is not good, the corns can be removed through surgery; if the corns are caused by foot deformity, it is necessary to perform surgery to correct the deformity in order to completely cure the corns. 3. Physical therapy: Smaller corns can be treated by freezing, laser and other methods. It is recommended that patients with corns on their feet go to a regular hospital in time and follow the doctor’s instructions for reasonable treatment. When using medication, strictly follow the doctor’s instructions to use medication, not blindly self-medication.
