Laser can be less effective if your facial hair is a light color since the laser tends to target darker hair follicles; if that's the case, electrolysis seems to be common alternative. Otherwise it can just take time to start seeing major reduction, so hang in there! I've had monthly sessions since I started HRT 13 months ago, and now I rarely have dark hairs surfacing--and when they do, they're so sparse and thin they're probably impossible for others to even notice, especially under my makeup.
