What is the difference between the way electrolysis works and the way laser works?
With conventional electrolysis, no matter what modality is being used, the target tissue in the hair follicle is the moist dermal papilla. This current, whether direct or alternating (RF), causes either a chemical reaction or heats up the moist tissue and destroys it. Great care has to be taken not to administer too much current that would affect the moist ground tissue of the dermis that surrounds the lower portion of the hair follicle. This layer of skin contains the collagen and elastin layers and can be irreparably damaged to being too aggressive with conventional treatment. The laser is different, because it's light is absorbed by the dark pigment producing cells at the bottom of the hair follicle. These are called melanocytes, which means they produce melanin. The heat from the melanocytes is then transferred to the adjacent vascular cells and the heat destroys these cells of the dermal papilla. Because there are no pigment cells in the adjacent dermis, the laser can be turned higher than conventional devices because there is no chance of damage.
