I used laser hair removal to address facial hair, but it wasn't very effective and the results were not permanent.
I completed all of the treatments recommended by the dermatologist. However, less than a year later, most of the hair came back. It is important to know the laser does not work on all hair. Unless there are significant advances in technology, the laser won't even reduce light brown or blond hair. Somehow the laser targets/sees the dark hair and doesn't see light brown or blond hairs. In my case, it definitely was not worth it. Perhaps I would have had better results if the hair I wanted removed had been close to black.
