Why is it critical to understand the laser-tissue interaction?

Understanding laser-tissue interaction is essential because it enables practitioners to select the appropriate laser and adjust the settings for effective treatments. Each type of tissue absorbs laser energy differently, which influences the choice of wavelength, pulse duration, and energy settings. If a practitioner knows how the laser interacts with skin, hair, or other tissues, they can optimize the treatment parameters to achieve specific clinical outcomes, such as hair removal or skin rejuvenation, while minimizing adverse effects. This knowledge directly correlates to patient safety, treatment efficacy, and overall satisfaction, which are critical components in the field of laser therapy.
