The rest is pulsed light technology that is not a permanent hair removal or a quick way to get rid of his hair, but is still a very effective method in the medium term.
I remember that this only works on neither too dark skin or if too light hair.
Then it is not safe, so I recommend taking the time to read the precautions and comply sun exposure and testing.
It is not compatible with UV sessions in the cabin or sunbathing on the beach.
It takes several weeks before a golden skin smooth, flash on a one session every two weeks. Do not throw away your razor too fast, anyway you need to prepare your legs (and other body parts) to be flashed. And at first, you will also probably need a razor between sessions.
I summarize the principle is shaved (if the flash burns the hair and the lamp is the risk of burning the skin together and damaging) and then flash. The intense light burns the hair to the roots, he fell after a few days and slower regrowth.
If your hair is racing beasts like mine, repeat sessions for several weeks before regrowth decreases and stops. But after this work shaving / flash, if not discouraged in the first weeks, the result is there, the hair grows more slowly and finally not at all. More ingrown hairs, or itchy legs that itch when hairs grow back, unsightly blackheads ... At least if one pursues the flash sessions once a month. If we stop, the hair eventually return, too bad.
So in the short term epilators that cut or tear their hair give results more easily and quickly. But ultimately pulsed light actually delivers smooth legs.
