Comparison of Picosecond Pulsed Nd:YAG Laser and Fractional Laser for the Treatment of Acne Scars

This study compares the application of a picosecond 1064-nm laser with a diffractive lens array with nonablative fractional laser for the treatment of acne scarring.

This trial is a 17-week, prospective, randomized split-face study that compares the results between two facial sides either receiving the picosecond 1064-nm laser or nonablative fractional laser treatment for atrophic acne scar.

Inclusion Criteria:

• Subjects with facial atrophic acne scars
• Subjects who observe the schedules and protocols of the clinical trial
• Subjects who give informed consent to participate in the clinical trial

Exclusion Criteria:

• Subjects who have active acne under treatment
• Subjects who had received any other treatments for acne scarring for 6 months prior to the first treatment
• Subjects who underwent other treatments including chemical, mechanical or laser resurfacing during the study period
• Subjects who have current acute illness
• Subjects who are considered inappropriate for the clinical trial under the judgement of investigators
