Which setting is important for ensuring laser treatment does not cause skin damage?

The fluence threshold is critical in ensuring that laser treatments do not cause skin damage. Fluence refers to the energy delivered per unit area, typically measured in joules per square centimeter (J/cm²). Each skin type has a specific threshold that must not be exceeded to prevent adverse effects such as burns or hyperpigmentation.

When appropriate fluence is applied, it ensures that the energy is enough to effectively target hair follicles or lesions without harming the surrounding skin tissue. This threshold accounts for individual variances in skin types and conditions, which helps practitioners tailor treatments to each client's specific needs.

While energy level, skin type, and time interval also play significant roles in laser treatments, the fluence threshold directly relates to the safe delivery of energy. Ensuring that the fluence is within the defined safe limits for a particular skin type is essential for both efficacy and safety in laser treatments.
