How Does It Work? Laser hair removal uses a monochromatic beam of light that bypasses the epidermis so it doesn't damage the skin and it dissembles the reproductive cycle of the hair within the follicle. It's a very quick and effective process, and one treatment on my bikini line only took about 10-15 minutes.
The GentleMax Pro machine (pictured above) happens to work on both light and dark skin, like most newer models. The laser for darker skin penetrates 5 millimeters, while the laser for light skin penetrates 3 millimeters — that's the only difference. The laser doesn't work on white hair, light blond hair, or light gray hair, because it recognizes dark hair. Think of a dynamite with a fuse (the fuse being your hair, the dynamite being the follicle): if the hair is dark, the light travels to the fuse, zaps the follicle, and it disables the reproductive cycle of the hair follicle.
How Many Sessions Are Recommended? Usually about six or more total sessions, depending on how coarse your hair is, four to six weeks apart. You can shave in between sessions, but waxing is not advised.
Does Laser Last Forever? Unless you have a hormonal imbalance, pretty much. Usually after those six sessions, you lose anywhere from, on average, 75 to 95 percent of your hair, as long as your hair has some pigment.
