Progressive disseminated essential telangiectasia and erythrosis interfollicularis colli as examples for successful treatment with a high intensity flashlamp

This study involved IPL treatments on patients with progressive disseminated essential telangiectasias and erythrosis interfollicularis colli. Both groups showed positive results after photographic evaluation by physicians.

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
