Why is the cooling stage critical in laser treatments?

The cooling stage is critical in laser treatments primarily because it minimizes thermal injury to surrounding tissues. During laser procedures, the energy produced can generate significant heat in the targeted area, which, if not properly managed, can extend to surrounding tissues and cause unwanted damage. Implementing a cooling stage helps to dissipate heat, providing a protective effect on the skin and underlying structures, thereby reducing potential side effects like burns, swelling, or hyperpigmentation. This step is crucial for maintaining patient safety and comfort while also optimizing the overall effectiveness of the treatment, as it allows for higher energy settings without risking greater damage to adjacent areas.

While the cooling stage may have benefits related to other aspects mentioned, such as improving outcomes in specific procedures or enhancing patient comfort, its primary function is to safeguard surrounding tissues from excessive heat during treatment.
