Studieoversikt
Detaljert beskrivelse
- 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%).
