During a treatment you and the technician will wear special glasses to filter out harmful light. The technician will evaluate you to determine your skin type  and decide how to set the laser appropriately. The technician may do some test spots before beginning actual treatment.

An experienced technician is able to adjust the laser according to your skin and hair type. The adjustments on the laser include 1) power – joules, 2) spot size – the area that can be treated in one and/or amount of cooling. These variables can often be adjusted to customize treatment for the client.
