Treatment should be performed with the highest fluence the skin can tolerate. Studies have shown that the percentage hair loss is fluence-dependent, with higher percentages of hair loss at higher fluences. Each skin type has its own threshold fluence at which pigmentation changes occur. To mini- mize hypo- or hyperpigmentation, lower fluences than those suggested above should be used while gaining clinical experience. With multiple pulsing the incidence of pigment changes increases without an increase in efficacy. For this reason, double and triple pulsing are not recommended. If hypo- or hyperpigmentation occurs, it is transient. The duration of these pigment.
