Power levels
The number of power settings provided by the laser epilator or photoepilator (see "Type").
The emitted light flashes from the epilator need to strike a balance between intensity and skin safety. Different situations necessitate varying levels of light intensity. For instance, addressing dark hair on light skin requires relatively lower power, while lighter hair demands a more intense approach. Sensitive or problematic skin might call for reduced intensity. The greater the power options in the device, the finer the adjustments possible for specific scenarios. Advanced models can offer as many as 5 to 6 options.
UV filter
A filter incorporated into the flashes of the photoepilator lamp to block ultraviolet radiation. Excessive exposure to this radiation can be detrimental to the skin and heightens the risk of burns.
Reusable flash
Possibility of operation of a photoepilator or a laser epilator (see "Type") in the reusable flash mode.
In this mode, each time the lamp is turned on, it does not emit a continuous pulse, but a series of short flashes. This way of working is considered relatively gentle and at the same time quite effective, especially when processing large areas.
Pulse interval
The time between two separate lamp flashes. The shorter the interval between pulses, the faster you can move the device and the less time the procedure will take.
Lamp life (flashes)
The photoepilator lamp has a guaranteed lifespan in terms of the number of flashes it can emit before it becomes depleted and ceases to function. Ideally, this number should be a minimum of 750 flashes (0.75K). In certain models, the lamp's longevity can extend to tens of thousands of flashes.
