What does thermal injury refer to in laser treatments?

Thermal injury in laser treatments specifically refers to damage caused by excessive heat. When lasers are used in medical or cosmetic procedures, they target tissue with precise wavelengths of light to achieve various effects, such as hair removal or skin rejuvenation. However, if the energy delivered by the laser is too high or the duration of exposure too long, it can result in overheating of the skin or underlying tissues.

This form of thermal damage can manifest as burns, blisters, or prolonged redness and irritation, affecting the overall healing process. It is crucial for practitioners to understand and control the parameters of the laser to avoid thermal injury, ensuring safety and effectiveness during treatments. Effective training emphasizes the importance of monitoring the treatment area closely to prevent excessive heat from causing significant damage, which reinforces the concept that thermal injury specifically deals with the consequences of high-temperature exposure during these procedures.
