Laser mole removal is another form of effective treatment. Most patients do not require anesthetic. Some patients have indicated that they feel a slight tingling when the laser pulses, or that the laser pulse feels like the snap of a rubber band against the skin. The laser works by sealing the blood vessels and evaporating the tissues they remove. Therefore, this eliminates the cutting and sutures on the skin. Scarring is often reduced in some cases. After laser surgery, a scab is formed where mole was previously and it will fall off within 2 weeks. A slight redness will be evident after the scab is gone and will disappear in time. Laser treatment is expensive and will need several visits in many cases to fully remove the unwanted mole.
