Women facial hair

Hi

I am 50 years old and have always have facial hair since I was 20.  But my hair is light so my facial hair was not as noticable when I was young but as I have aged my facial hair is really bad.  I spend so much time trying different products.  I used the women's facial shaver for about a month and that was a big mistake because now my hair comes in thicker and has spread over just about my whole face instead of just my chin.  It did this because I decided to use the shaver on my cheeks one day.  I have tried Nair, Neet, waxing, tweezing and nothing works for more than a day or two.  I actively work with the public and this problem is really bothering me.  I went to electrolysis and doctor told me it was not for me because that works on people with dark hair and my hair is light brown and white.  Please tell me how I can slow growth or get rid of this problem.
