A mole is a pigmented spot located on the surface of the skin. There are many types of moles that have different colours, shapes and sizes.They are common amongst many people and are usually nothing to be concerned about.
When cells (melenocytes, which is the cell that gives the skin pigmentation) in the skin evolve and grow into clusters it causes a mole to be formed.
This treatment involves applying a very fine jet of cryogen (cooling fluid) to the mole. This will freeze the mole and leave the surrounding tissue unaffected. The freezing temperature will restrict any blood supply to the mole as well as killing the cells in it. As a result the mole will scab and after about 10 to 14 days the mole will fall off, and the skin underneath will be healed.
