The minimum amount of time between IPL treatments is usually 3 weeks.  This allows "damaged pigmented" lesions to absorb completely.  Initially the sunspots turn darker because of the heat generated from the laser.  The body sees this damaged, darkened pigment as debris and needs to be removed.  This removal process can fully take up to 3 weeks.
