Overlapping
If you suspect your system has an effective spot size smaller than the physical spot size of your handpiece light guide then you should consider overlapping the spots during treatments, by around 20 to 25%.
This is quite safe (with most systems) since treating the same area twice in quick succession is not usually a problem (as long as there is proper skin cooling). There is a commonly held myth that such a procedure is potentially dangerous. This is not true – however, some poorly designed systems may induce excess skin damage, even in the small overlapping regions.
It will become obvious pretty quickly whether your system induces such problem.
