The Laser Parameter Puzzle: Mastering Settings for Safer, More Effective Treatments
Presenter: Petrane Reddick
Presentation Synopsis
Laser treatments are highly dependent on thoughtful parameter selection and an
understanding of how laser energy interacts with the skin, hair, and target chromophores.
Choosing parameters based solely on a device’s preset settings may not adequately
address individual differences in skin type, hair characteristics, treatment area, treatment
history, or clinical response.
The Laser Parameter Puzzle: Mastering Settings for Safer, More Effective Treatments
is a 100-minute interactive continuing education program designed to strengthen the laser
professional’s understanding of the relationship between laser parameters, tissue response,
treatment goals, and patient characteristics.
Participants will explore laser-tissue interaction, wavelength selection, fluence, pulse
duration, spot size, cooling, treatment intervals, and factors that influence laser hair-removal
outcomes. Special attention will be given to considerations for treating skin of color and
reducing the risk of unwanted thermal injury and pigmentary complications.
Through clinical scenarios and case-based discussion, participants will practice applying
laser principles to real-world treatment decisions rather than relying solely on preset
parameters.
Learning Objectives
At the conclusion of this presentation, participants will be able to:
1. Explain the basic principles of laser-tissue interaction and selective photothermolysis as they relate to aesthetic laser treatments.
2. Identify the primary laser parameters—including wavelength, fluence, pulse duration, and spot size—and describe how each can influence treatment outcomes.
3. Discuss the relationship between wavelength and target chromophores when selecting laser technology for skin and hair treatments.
4. Evaluate patient-specific factors, including skin type, hair characteristics, treatment area, tanning history, and previous treatment response, that should be considered before selecting or modifying treatment parameters.
5. Describe how fluence, pulse duration, spot size, cooling, and treatment intervals may affect the efficacy and safety of laser hair-removal treatments.
6. Recognize clinical factors that may contribute to inadequate treatment response, including inappropriate parameter selection, hair characteristics, treatment timing, and patient-related variables.
7. Identify important considerations when performing laser treatments on individuals with higher Fitzpatrick skin types and increased epidermal melanin.
8. Recognize common unwanted responses and potential complications associated with laser treatments and identify factors that may contribute to their development.
9. Apply laser principles to patient case scenarios to determine which clinical factors should be evaluated before changing treatment parameters.
10. Demonstrate improved clinical decision-making by integrating laser physics, tissue response, patient characteristics, and treatment history when developing a laser treatment approach.
