Quite some time back, and I do not know if I read this in Heloise's daily column or Ann Landers, but regardless, they said to just shave it. I was shocked to hear that women actualy shaved their facial hair. They stated that it works and that, no, your hair will not come back in coarse like a man's beard.
I have a girlfriend who tried everything under the sun, and paid a fortune for numerous treatments. She finally decided to do this and has been doing it ever since. She mentioned she does it when she takes her shower and only has to do it at most, a couple times a week.
Hope you find the way which will provide the best results for you.
