What Are the Results?I've done three treatments to my bikini line using the Tria, and have to say I'm very impressed so far. Giving an eyeball estimate, I would say there has been about a 70% reduction in hair where I used the highest setting. (Tria originally had three settings, but now has five). Mostly all hairs making up that 70% hair reduction aren't growing in, very few within that same group have grown back so fine and light that you can't see them, but can feel them a bit when touching the skin.
Where the medium setting was used deeper in my bikini line, I would say the hair reduction is more like 55% - 60%. A lower percentage was expected because the second setting gives off less heat to destroy the hair follicle. I never used the lowest setting anywhere in my bikini line.
Tria Pain FactorLaser hair removal is supposed to get less uncomfortable the more times you get the treatments because some hairs are already destroyed. Now everyone is different, but that didn't happen with me. All three treatments were the same amount of discomfort. The bikini area is a very sensitive zone, so that may have something to do with it. I wouldn't call the feeling exactly painful, but don't make the same mistake I did and use the laser when you're getting ready for bed. It's not really something you would find relaxing.
Cordless Laser: Convenience or Hassle?Tria needs to be charged, so it can be used cordless. I did like that when you have to twist and turn the laser to different angles there are no cords getting in the way, and no need to worry about being close to an outlet. The challenge is that you only get about ½ hour of time to use the laser, and it needs to be charged again. Re-charging the device takes about two hours, so if you're treating big areas like your legs, the sessions would be cut into many times.
