Complications of laser hair removal-How we could reduce them?

Laser hair removal became a very popular intervention, with a permanently increasing number of procedures being performed worldwide. The procedure is often performed by nonmedical personnel, and even by untrained personnel, that could be associated with different kind of adverse events, from mild to serious. The complications associated could be lower if the operators understand the basic of laser physics and the working principles of devices. We propose a simple acronym, WATCH, in order to increase the safety and efficiency of laser interventions.
