An increase in fluence leads to an increase in what?

Fluence, in the context of laser treatments and electrolysis, refers to the energy delivered per unit area, often measured in joules per square centimeter (J/cm²). When fluence is increased, it typically means that more energy is being concentrated on a specific area over a given period of time. This additional energy results in a rise in temperature within the targeted tissue or area because increased energy can lead to greater absorption and conversion to heat.

In procedures like laser hair removal or skin resurfacing, this increase in heat can enhance the effectiveness of the treatment by targeting and damaging the hair follicles or skin cells more precisely. It's critical for practitioners to manage fluence levels carefully to ensure optimal results while minimizing the risk of damage to surrounding tissues. Hence, the correct association with an increase in fluence is indeed an increase in heat, as the energy becomes more concentrated and effectively raises tissue temperature.
