BACKGROUND AND OBJECTIVE: To evaluate the effects on disruption
of hair growth of the non-coherent filtered flashlamp intense
pulsed light (IPL) source.
MATERIALS AND METHODS: Twenty-eight sites on 23 patients with
Fitzpatrick type I-III were enrolled using a single treatment
IPL followed for three months post-treatment. Another 56 on 48
patients with Fitzpatrick skin types I-V randomly enrolled for
two treatments one month apart and followed for six months.
STUDY DESIGN: Prior to beginning treatment and at each follow-up
visit hair counts were obtained by averaging three 1-cm2 areas
on a clear acetate template placed over the skin. Repeat hair
counts and photographs were obtained at 2, 4, 8, and 12 weeks
for the single treatment protocol and at additional 4, 5, and
6 months for the double treatment protocol. Parameters utilized
were a 2.8-3.2 millisecond pulse duration typically for three
pulses with thermal relaxation intervals of 20-30 milliseconds
with a total fluence of 40-42 J/cm2.
RESULTS: For the double treatment protocol hair clearance of
64% was achieved immediately following the second treatment. By
week 8 reduction of hair counts was 42%. At 6 months, hair counts
were reduced by 33%.
CONCLUSIONS: Non-coherent IPL is an effective modality for long-term
hair removal. IPL is safe with minimal side effects of epidermal
injury or pigmentation change.
