Electrolysis is a way of removing individual hairs from the face or body.
A very fine sterilized needle is inserted into the hair follicle, which is a natural operning in the skin. The skin is not pierced or broken.
Once the ﬁlament has been inserted, a small amount of current is applied. The current cauterizes the papilla, which is the tiny capillary responsible for causing the hair to grow. The current loosens the hair within the follicle, so with tweezers, the hair slides out effortlessly.
Eventually, the blood supply to the hair is completely destroyed, and the follicle cannot produce another hair.
