Abstract

Objective

To evaluate the efficacy and safety of a thermo-mechanical fractional device for the treatment of photodamaged skin.

Methods and Materials

Twenty-five subjects received three thermo-mechanical fractional device treatments at monthly intervals. Low treatment settings of a 5 ms pulse duration and 100 μm tip protrusion were administered in 1–2 passes. Digital images were evaluated for improvement on the Fitzpatrick Wrinkle Classification Score 3 months after the final treatment. Secondary efficacy endpoints included ratings on a Global Aesthetic Improvement Score and Subject SatIsfaction Questionnaire.

Results

Forty-eight percent of subjects demonstrated a ≥ 1 score improvement in the Fitzpatrick Wrinkle Classification Score, and 96% of subjects demonstrated a good to excellent Global Aesthetic Improvement Score. Sixty-eight percent of subjects were “satisfied” to “very satisfied” with treatment results.

Conclusions

The thermo-mechanical fractional device at low settings is safe and effective for improving signs of photodamage with minimal patient discomfort.
