-What is a good device?
There are three parameters in a hair removal device, energy, pulse width and frequency. All we need to know is the pulse width to use when operating the device. The smaller the pulse width is, the better the device is in terms of achieving the energy effect. This is the same reason with the super picosecond, both are narrow pulse width, strong energy. The difference in price between Paleo and Ultra Picosecond is that the Ultra Picosecond has a small pulse width, but the energy is still very strong.
The pulse width that our body can accept is within 40ms.
-Good device vs. poor device - What is pulse width?
If we are careful to observe, you will find that the pulse width of the cheap epilators is basically adjusted to about 100ms, and the energy is also adjusted to a particularly high level. To adjust the total energy one-third or even one-half or more. This kind of hair removal instrument, not only the experience is not good, the effect is not ideal. Those very good and expensive epilators, such as the epilators in Beijing, the pulse width is very small, all within 40ms, at the same time, when operating, the energy does not have to be adjusted to a very high level, the pulse width and energy are within 1/10 of the total.
-What is pulse width?
Pulse width is the amount of time the energy output remains on the skin. For example, a match is struck quickly across our arm and a match is struck slowly across our arm. The length of the stroke is the pulse width. The smaller the pulse width, the shorter the dwell time (fast stroke). The larger the pulse width, the longer the dwell time (slow stroke). The faster the stroke, the better the experience, the slower the stroke, the risk of burns.
-Summary.
When we choose a hair removal instrument, under the condition that we can achieve the effect, we choose the kind of pulse width not more than 40ms, and the smaller the pulse width, the better. At the same time, the pulse width and energy parameters should not be more than one tenth of the total parameters (for example, if the pulse width parameter is 1-400ms and the energy parameter is 1-150J/CM, we will choose the one with pulse width of 40ms or less and the energy of 15J/CM or less).
The unit of pulse width is ms, the unit of energy is J/cm, and the unit of frequency is HZ.
