Progressive Disseminated Essential Telangiectasia and Erythrosis Interfollicularis Colli as Examples for Successful Treatment with a High Intensity Flashlamp


PubMed Reference: Wenzel SM, et al. Dermatology. 2008;217:286-90.

Study Details: 

  • 4 subjects (3 females, 1 male; mean age 49.3 years) with progressive disseminated essential telangiectasias on the extremities & 5 females (mean age 48.6 years) with erythrosis interfollicularis colli (also known as poikiloderma of Civatte) on the neck / décolletage
  • IPL treatments (555-950 nm): 10x48-mm spot size; fluence 14-17 J/cm2; pulse durations of 14 ms
    • 1 subject with Fitzpatrick Skin Type I treated with 530 nm cut-off filter and lower fluence of 11.7 J/cm2 (neck) & 13.1 J/cm2 (décolletage) after hyperpigmentation with VL handpiece
  • Photographic evaluation by treating physicians, based on 6-point scale: 0%, 1-25%, 26-50%, 51-75%, 76-    90% & >90%

Study Results: 

  • 100% of subjects with disseminated essential telangiectasia showed excellent results (76-90%improvement) after multiple treatments (average 2.8)
  • Subjects with erythrosis interfollicularis colli showed clearance rates of 76-90% (n=2), 51-75%(n=2) and 26-50% (n=1) after 1-4 treatments
  • Adverse effects were limited to test spots and didn’t recur after a reduction in energy for treatments
  • No posttreatment intracutaneous hematomas
