This is the only medically approved form of permanent hair removal.

Electrolysis has the longest-known track record together with the most effective results for hair removal.
Electrolysis is performed by inserting a very fine, flexible needle into the follicle (the pocket where the hair sits in your skin). A tiny amount of current is then skillfully applied, destroying the lower part of the follicle, which stops any more hairs growing from that particular follicle.
