Thank you, and i hope to hear from you. The only currently reliable technology for removing facial hair is good old fashioned electrolysis. This involves a trained individual carefully inserting a microscopic electric wire down into each and every single hair follicle, one at a time, and frying the cell at the bottom that manufactures hair. It hurts a bit, to some quite a bit, but it actually works. Now problems occur when the electrologist is not skillful, well trained, or is just plain uncaring or unprofessional.
Problems can also occur when the client becomes too demanding.
Like every profession, there are good and poor individuals to be found. Damage to the face by electrolysis results in pit scars, not unlike the surface of a golf ball, in the worst cases. This is caused by having to much work, or poor work, done too often. The skin does not have time to heal, and the damage becomes cumulative. Over all, the important thing here is to understand that electrolysis takes time.
