The laser treatment of flat warts usually takes about 2 weeks to recover, but each patient’s physical condition and post-laser care are different, so the exact recovery time can not be generalized. The laser treatment of flat warts can vaporize the warts through the vaporizing effect of the laser, and the affected area will gradually scab over and heal. If the patient is in good health and has proper post-laser care, the affected area will gradually recover in about 2 weeks after the laser treatment. If you don’t take care of the warts properly, you may have to irritate the warts again and again, which may affect the speed of recovery and even lead to infections in the warts. The recovery time for flat warts after laser treatment cannot be determined, if the wound is red, swollen and itchy during the recovery period, it is recommended that the patient go to the hospital for treatment.
