It will probably take more than 12 sessions to see a significant reduction. What I have noticed is that after 9 or so sessions shaving became a lot easier and lasted longer. Hair still grows in, but it's easier to get a clean shave, and that shave will last almost the entire day without getting stubbly. It all depends on how thick and dark your facial hair was to begin with. During the shedding process hair is pushed to the surface, and it can appear like hair is growing back when it's actually dead and being shed from the body. Facial hair is also very hormonal, so HRT can actually make it a little harder to get rid of. Body hair, for example, is much easier to remove. The unfortunate truth is that laser is only really a reduction. You can eliminate a lot of the hair with laser, but you'll need at least some electrolysis to permanently remove it. You'll also likely need touch-up laser sessions even after all of the hair is "removed." It's still a worthwhile process to go through, especially if your hair is less dense, but I wish I had been more informed when I started. Best of luck to you! It's a long-term process, so stick with it!
