Two factors favour laser over electrolysis: time and comfort. While electrolysis is effective, it works by inserting a tiny needle into each hair follicle, one at a time, and delivering a jolt of electricity and/or radio frequency energy. In contrast, the size of the treatment window on the laser head allows the laser to disable many hair follicles in a single pulse. We can treat an entire upper lip in five to nine quick pulses, while an electrolysis would take up to hundreds of precisely placed “zaps” to cover the same area. Just think of the time commitment involved in larger areas, such as a back, bikini or full legs! In addition, you experience a less painful sensation with the laser.
