I remember browsing here before and finding a lack of success posts, so here is one briefly!
I am 19, female, and quite dark-skinned and had a lot of dark brown facial hair, and decided to have laser done on the upper lip. I started out with IPL which I do NOT recommend as it didn’t seem to do any good at all. I moved to proper laser, have had 7 treatments in total, and can see an 80% reduction (it has been 7 months since my last treatment).
The laser does not pick up all the hairs, so be prepared for that, but the only hair coming back through is light and unnoticeable- I just remove it with cream every 10 days or so. I am going for two more sessions later this year to make sure it’s done all it can, but will probably finish up with electrolysis someday when I can afford it. The hair is causing me absolutely no problems anymore though.
Good luck to anyone on the same road!
