CASE STUDY 1

  • 43-year-old male patient with Fitzpatrick Skin Type III treated for 8x11-cm2brown patch with terminal hairs (Becker's nevi) on the arm and elbow
  • 2 laser hair removal treatments (8-week interval) with 1,064-nm LPND (GentleMax): 18mm spot size, 3-5 ms, fluence 10 J/cm2, DCD (30/20) 
  • 8 NAFR treatments (4 to 8-week intervals) using the 1,550-nm erbium-doped laser (Fraxel DUAL): 15mm, 9-40 mJ, 14-20% coverage, cold-air cooling 5, 8 passes
  • >95% clearance by independent clinical and photographic assessment.

CASE STUDY 2

  • 28-year-old female patient with FST IV treated for large brown patch with terminal hairs (Becker's nevi) on the back
  • 3 laser hair removal treatments (4 to 8-week intervals) with 1,064-nm LPND (GentleMax): 18mm spot size, 20 ms, fluence 14 J/cm2 , DCD (40/40) 
  • 5 NAFR treatments (4 to 8-week intervals) using the 1,550-nm erbium-doped laser (Fraxel DUAL): 15mm, 30-45 mJ, 20% coverage, total 1.74-2.10 kJ, cold-air cooling 5, 8 passes
  • >75% clearance by independent clinical and photographic assessment at 3-month follow-up.
