Flat warts are a common dermatological disease that often appear on the face, neck, and backs of the hands, caused by a viral infection of the skin. For the treatment of flat warts, it is suggested to use laser, cryotherapy, or oral interferon medications. If one aims to completely eliminate flat warts, using laser and cryotherapy is relatively effective. However, no matter the method, there is always a possibility of recurrence. Thus, it is crucial to enhance one's own immunity. Additionally, it is advised to eat more vegetables and fruits in the diet.
