* 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%).
