Hi there,
When I first started facial hair removal, I went to Lori at the Papillon Center in New Hope, PA. I had about 15 hours done with her, which considering I only grew facial hair on my upper lip and a little on the chin, was a good amount. Lori was a skilled and friendly operator, and I did not experience any permanent facial scarring. My face was very red, and would scab up for the next few days, and then would return to normal. So as others have mentioned, with a skilled operator, it is possible to experience no scarring. However, having transitioned years ago, having to grow my hair out long enough for electrolysis was emotionally very distressing and embarrassing for me. I basically hid away in the home for days and would make the drive to the center wearing a surgical mask to and from the center to hide the facial hair. I also have a very low pain threshold, which made even the application of anesthesia with the long needle they use make me break out in tears and cry. I knew I couldn't stand the emotional and physical pain of electrolysis for much longer and researched laser hair removal.
Since I had black hair and light skin, I then opted for laser hair removal. While it is not considered "permanent" and some hairs do grow back, they grow back much softer and lighter and very wispy; and not much comes back when they do. If you are a good candidate for laser hair removal, I would suggest doing about 5 or 6 sessions of laser hair removal then using electrolysis to "touch up" the remaining hairs that grow back after the laser sessions. An added perk of laser hair removal is, if you are like me and hate growing out facial hair for electrolysis, laser treatments require you to shave before hair removal, which greatly reduced the embarrassment I felt when I grew out my facial hair for electrolysis.
In the area where we live, facial laser hair removal is pretty cheap. It cost $175 for the first treatment, and drops in price each subsequent treatment until the final treatment is only $50. Touch ups were $35. You do get the occasional wispy hair growing, but they are easily shaved off or can be permanently removed with electrolysis. Of course if you opt for laser, you should do research to learn about the reputation of the business and the laser they use for the removal. Not all lasers are created equal.
