It is undeniable that many hairs grow thinner and are virtually invisible even as parts of the body and the anterior hair removal mode. We must have patience, sessions to be made every 15 days at first, then spaced 3 to 4 weeks. I am doing more than one-off adjustments.
Note that I've always used the maximum power, albeit slightly more painful but more efficient. I do not use the multiflash because I find that the device tends to heat in this mode. I'm just the "piecemeal" pending although the small light turns back on. Do not want to go too fast and, in this way, the device does not get too hot. When this is the case, I turn it off and on again soon ... and continue without waiting (so no waste of time).
I use a gel for hair removal (before and after) for cooling the treatment area.
In conclusion, I find the value of this entirely fine device, but being fully aware that its effectiveness requires patience!
