Abstract

Background: Laser test spots are a preliminary assessment performed on a small area of the skin to evaluate patients' reaction to laser therapy. Despite their recognized importance, there is a gap in knowledge among dermatologists regarding laser test spot practices.

Objective: The authors aim to explore dermatologists' test spot practices.

Methods: A survey was performed among Association of Academic Cosmetic Dermatology members.

Results: Laser test spot practices varied widely between dermatologists, with 3.0% "always," 22.7% "frequently," 54.5% "occasionally," 16.7% "rarely," and 3.0% "never" performing test spots. Most dermatologists (59.4%) wait more than 2 weeks before evaluating a test spot. Furthermore, 68.3% of the respondents use the same laser settings for the test spot as they would for the actual treatment. Regarding location, 60.9% of dermatologists perform laser test spots in the same area intended for treatment, while 39.1% choose another inconspicuous area.

Conclusion: Establishing definitive protocols for laser test spots may reduce variability in practice and enhance the overall safety and efficacy of laser treatments.
