Fractional CO2 Treatment of Acne Scars in Asians (CO2)

The objective of this study is to investigate the efficacy and side effects of a fractional CO2 laser for treatment of acne scar in Asians.

The objective of this study is to investigate the efficacy and side effects of a fractional CO2 laser for treatment of acne scar in Asians. Study hypothesis Reduction in acne scars based on blinded evaluation of before photos and the one and three month follow-up photos after four full face Ellipse Juvia with low density treatments with a fluency of 90-105 mJ/MTZ is statistically significant (5%). The direct clinical blinded evaluated reduction in acne scars based on before photos and the patient in life, by the one and three month follow-up is statistically significant (5%) Reduction in fine lines based on blinded evaluation of before photos and the one and three month follow-up photos after four full face Ellipse Juvia with low density treatments with a fluency of 90-105 mJ/MTZ is statistically significant (5%). The direct clinical blinded evaluated reduction in fine lines based on before photos and the patient in life, by the one and three month follow-up is statistically significant (5%). Reduction in pigmented disorders based on blinded evaluation of before photos and the one and three month follow-up photos after four full face Ellipse Juvia with low density treatments with a fluency of 90-105 mJ/MTZ is statistically significant (5%). The direct clinical blinded evaluated reduction in pigmented disorders based on before photos and the patient in life, by the one and three month follow-up is statistically significant (5%). Improvements in skin texture and pore size based on blinded evaluation of before photos and the one and three month follow-up photos after four full face Ellipse Juvia with low density treatments with a fluency of 90-105 mJ/MTZ is statistically significant (5%). The direct clinical blinded evaluated reduction in skin texture and pore size based on before photos and the patient in life, by the one and three month follow-up is statistically significant (5%).

the treatment settings: Pulse duration : 5 to 7ms depending on skin reaction Spot Density: 49 MTZ/cm2 (Low density) Power: 15 W = (75 - 105) mJ/MTZ

by the clinical investigator and graded into one of six categories: worse, no effect, slightly better, fair, good, and excellent. The results shall be reported.

The outcome and degree of satisfaction based on the before photo is evaluated by the patients themselves
