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.
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.
Skin type sensor
An automatic sensor that identifies the skin type being treated by the photoepilator. Individuals have varying skin types, which vary in sensitivity and color, influencing the selection of the best operational mode for the photoepilator. The sensor simplifies configuration by supplying essential data.
Usage for face
The possibility of using a photoepilator to remove facial hair. The facial areas have their own characteristics (for example, the skin is usually lighter) and require a separate mode of operation, which is provided in photoepilators with this function.
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.
