Photoepilation Results of Axillary Hair in Dark-Skinned Patients by IPL: A Comparison Between Different Wavelength and Pulse Width

Abstract

An IPL source removing 45 nm of the emitted spectra and applying a longer pulse width was found to provide a safer and more effective means of photo-epilation in Asian patients.

Variable pulsed light is less painful than light-emitting diodes for topical photodynamic therapy of actinic keratosis: a prospective randomized controlled trial

“…3,14,15 Incoherent polychromatic filtered flashlamp (intense pulsed light, IPL) devices developed in the early 1990s have been standard light sources for the treatment of several skin conditions such as vascular lesions 16 or photoageing, [17][18][19] or for hair removal. 20,21 The emission spectrum of IPL devices ranges from 500 to 1300 nm. With the aid of convertible cut-off filters, the IPL device can easily be adapted to the desired wavelengths, which underlines its high versatility.…”

Intense pulsed light

“…By the use of different filters, a wide range of wavelengths are possible for IPL systems. 2 There are an increasing number of reports of utilizing IPL by itself or combining it with other modalities for a variety of indications, including photodamaged skin. Hedelund et al 3 studied 28 women who received 3 IPL treatments at 1-month intervals.…”

Hair Removal

“…It may be possible that repetitive treatments with the ruby laser and IPL are capable of inducing long-term hair reduction as well; although the actual long-term evidence is sparse for IPL devices and varying results have been reported from ruby laser treatments. Further documentation is required, especially on the long-term efficacy of IPL treatments [32]. The overall results from long-term studies with the alexandrite, diode, and Nd:YAG lasers vary considerably in controlled trials, but show on average 50% hair reduction from repetitive treatments with these devices at 6-20 months after treatment [16,22,30,31].…”
