1. Start of the pulse emission. The hand piece moves over the hairy skin and emits three pulses per second.
2. The temperature in the dermis rises. The epidermis is not strained, since the single pulses only have low energy and the contact area (sapphire) is intensely cooled.
3. Through the large number of pulses per area a high amount of energy is accumulated in the dermis. The hair-growth cells are thus heated to a clinically acceptable temperature in order to kill them off. All types of hair thickness and all pigmented hair can be successfully removed through that method.
