I have only just come on to this thread.
When I was in my early 40s, I had laser treatment on my upper lip, chin, hairline area. It took about a year, was expensive, but the result is that more than 20 years later, I have no facial hair at all. Indeed, I have almost no hair on legs or underarms either, although that is a mystery. A full head of hair otherwise.
I wish that laser had been available to me earlier as facial hair plagued my teen age years and only lightened up when I was on the pill. My DH and friends have claimed that they never noticed it but I knew it was there and it made me miserable. My younger self tried all available methods--except shaving. Years of hair removal creams, electrolysis, then waxing, then bleaching only provided temporary removal.
Laser, in a reputable place, if the hair is dark, works very well and worth the money.
