Common warts are benign growths caused by human papilloma virus infection of the skin mucosa. The main use of topical drug treatment, cryotherapy, surgery or laser and other methods to remove. 1. Topical medication: Commonly used medications include retinoic acid cream; fluorouracil ointment; imiquimod ointment, phthalamide cream, etc. 2. Cryotherapy: Cryotherapy is the application of liquid nitrogen to warts. It takes about a week for the warts to fall off on their own. The disadvantage is that the results are not always obvious at one time and the treatment may need to be repeated. 3. Surgery: Surgery is used directly to remove the lesion. The disadvantage is that it may leave scars on the treated area. 4. Laser treatment: Currently, it is possible to use pulsed light to cauterize the lesion and use the heat energy to make the wart fall off. The advantage is that the treatment can be precise, but the repair period is longer, and the pain is obvious. It is recommended that patients go to the hospital in time and choose the appropriate treatment method under the guidance of the doctor.
