Arms	Assigned Interventions
1: Experimental Fractional CO2 laser resurfacing	Device: Fractional CO2 Laser 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

Detailed Description:

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
1. 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%).
2. 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%)
3. 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%).
4. 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%).
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%).
6. 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%).
7. 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%).
8. 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%).
