EPILATION RESULTS COMPARISON: DIODE LASER VERSUS IPL. THE EFFECTIVENESS
OF DIODE LASER EPILATION FOLLOWING NON-COHERENT LIGHT THERAPY
Izabela Zaleska

Lasers and IPL action is similarly based on the selective photothermolysis principle, where melanin acts as
chromatophore. There are, however, fundamental differences in the way they’re built and in the light they
emit.
LASER (Light Amplification by Stimulated Emission of Radiation) emits monochromatic light, with little discrep-
ancy, coherent over time and distance and with significant power density.
IPL (Intense Pulse Light) on the other hand emits intense, pulsing, polychromatic light which is non-parallel and
has no fixed wavelength.
Epilation has been the subject of numerous scientific papers, mostly comparing various kinds of lasers while
none has defined the relation between coherent and non-coherent light.
The goal of this paper is to compare the results of epilation treatments by laser and by IPL and to rate the effec-
tiveness of diode laser epilation following non-coherent light therapy.
The results do not surprise. A percentage average of hair loss among patients treated with diode laser is higher
which indicates laser’s higher effectiveness.
IPL has been shown to negatively impact the effectiveness of diode laser. This is linked with the way non-co-
herent light weakens and thins the hair which impedes the absorption of laser light by melanin and adversely
affects treatment results.
