Laser hair removal deliver very fast results, but is not recomended for dark/brown skin. I got burned, and now after 10 treatments i have PIH en face and legs. So if you got very sensitive skin, of are propense to develop PIH, NOT LASER.
Now i'm trying IPL treatment for hair removal and to treat PIH en diferent wavelenghts, plus hydroquinone 4%. I got 4 months trying to recover my skin, and i got lucky that i did not get permanent damage in my skin.
So be carefull with lasers. The problem with sensitive skin is the time of exposure to the laser, that produces burns.
