Scientific research

Keen to demonstrate the scientific basis of its technological applications, Dectro International went, 
in 2013, to the LOEX Center of the Université Laval. Combining the expertise of the LOEX 
(Laboratoire d’Organogénèse expérimentale) doctors with Dectro International’s technologies, 
two studies were conducted to prove the efficiency of the 27 MHz radiofrequency in electroepilation 
and the IPL’s in photoepilation.

27 MHz Thermolysis

Electroepilation is a frequently used method for hair removal and is considered permanent. 
We should however note that there is a paucity of histological studies on the effects of radiofrequency (RF) on hair follicles.

The objective of this study was to observe the destruction of human hair follicles and surrounding 
tissues after a treatment with 27 MHz RF, with special attention to the bulb and bulge/dermal papilla regions. 
Significant damage was observed on the hair follicles. The location of destruction areas varied, depending on 
the point of insertion of the probe, while the epidermis remained intact.

Photoepilation with intense pulsed light

Intense pulsed light sources have been successfully used for hair removal, but long-term hair 
reduction may require several treatments. Many questions remain regarding the impact of IPL treatment 
on the structure of the hair follicle, more specifically on stem cells and dermal papilla cells. 
The objective was to characterize the destruction of human hair follicles and surrounding tissues 
following IPL treatment, with more attention paid to the bulge and bulb regions.  Histological analysis 
confirms that pigmented structures, such as the cells of the bulb (melanin-rich) and hair shaft, are 
the principal targets of the IPL treatment, whereas white hair and epidermis remain intact.
