As an ftm who was made by his mom to do laser removal because of his facial hair, I didn't think it worked well for actually removing hair. I started shaving and my hair grew back, and I went for 2 years. You can stop going when your done but every once in a while you will need a touch up.
But it does make your face smooth so I guess thats a plus. I didn't think it hurt that bad, electro was worse, but numbing cream made it better. i just wish I could remember the name.
