What is the function of a cooling mechanism in laser devices?

The primary function of a cooling mechanism in laser devices is to protect the skin and reduce discomfort during treatment. Laser procedures can generate significant heat, which may cause pain or damage to the skin if not managed properly. Cooling mechanisms work by either pre-cooling the skin prior to the delivery of laser energy or actively cooling the skin during and after the treatment. This helps to minimize the thermal effects on the epidermis, allowing for a safer and more comfortable experience for the client. Enhanced comfort leads to better patient tolerance of the treatment, thereby making the overall experience more effective and satisfactory.

While other functions related to treatment efficiency and efficacy might be indirectly affected by cooling (such as potentially allowing the practitioner to use higher energy settings safely), the most direct and critical role of a cooling mechanism specifically focuses on skin protection and pain reduction.
