What is the effect of increased heat due to higher fluence during laser treatment?

Increased heat due to higher fluence during laser treatment leads to increased damage, which can be understood within the context of how lasers interact with tissue. Fluence refers to the energy delivered per unit area, and higher fluence means that there is more energy being concentrated in a smaller area of tissue.

When the energy delivered by the laser is high, it can result in the destruction of targeted cells or tissues more effectively. This is particularly relevant in cosmetic procedures such as hair removal or skin resurfacing, where the objective may be to destroy hair follicles or to vaporize the upper layers of skin. While this increased damage can be beneficial for achieving the treatment goals, it can also mean a higher risk of side effects if not applied properly.

Understanding this concept is important in determining the appropriate settings for laser treatments to effectively balance efficacy with safety. Higher energy levels must be carefully calibrated to ensure that the desired therapeutic effects are achieved without causing unnecessary harm to surrounding tissue.
