Corns on the hands can be removed through medication (such as corns cream, salicylic acid ointment, etc.), physical therapy (such as cryotherapy, etc.) and surgery. 1. Medication: For smaller corns, corns can be sterilized, soaked and softened, and then coated with corns ointment to make them fall off. Patients can also apply ointment with keratolytic effect locally, such as salicylic acid ointment, urea ointment, etc., after cleaning the affected area. 2. Physical therapy: patients can also go to the regular medical institutions, choose the liquid nitrogen freezing method or laser treatment method to remove corns. 3. Surgery: For those who are in serious condition and the medication is ineffective, they can wait for the inflammation to subside and then undergo corns excision. The prognosis of corns after treatment is good, and it is recommended that patients go to the hospital in time and receive standardized treatment under the guidance of doctors.
