Patent concerning the photoepilation of white hair

White hair patent

The work of the Research and Development division of EFB led to the filing of 15 patents on pulsed light. This technology is today implemented in every single EFB beauté device models.

Some examples of patents:

1/ Patent on white hair photo-epilation
The standard process for the photo-epilation of dark hair is not effective for the removal of white and blond hair because the latter does not absorb any light.
A new technology was therefore developed and clinically tested by EFB in 2004 then patented (*) in 2005.

This technology, which is protected by patent, is exclusively reserved to the users of EFB beauté® (*) equipment.

2/ Patent on a system that compensate the energy level ensuring a constant power from the first to the last flash

3/ Patent on an absorbing optical filter to maximize efficiency and constant security.

4/ Patents on the handpiece to prolong its life, safety and ease of use.


Applicator patented

All researches conducted by the EFBs engineers, tests and techniques used enable EFB beauté maintain a significant technological edge in the market.


The EFB beauté® technology which enables the photoepilation of white and blond hair is deployed by the Anthélia® range for the medical sector, and by Ariane® and Adéna® for the beauty sector.

(*) NB: copying and counterfeiting is reprimanded by 3 years of imprisonment and a fine of 300 000€.

IPL Range EFB beauté

The "visiting card" joulemeter


In order to enable the reliable measurement of energy supplied by IPL equipment, EFB has developed and patented a joulemeter in a visiting card format weighing just a few ounces.

Eurofeedback Joulemeter

The joulemeter (which surprises with its simplicity) offers an objective way to measure the true fluence of flashes emitted by the various machines available on the market.
This product enables users to check the true level of energy and the stability of light energy generated by flash lamps. Thanks to this tool, you are at last able to observe the difference between the excellent stability of energy ensured by EFB beauté® machines and by the others.

It is essential to note that the light energy generated by IPL equipment is an essential condition for performance but that is not alone sufficient to ensure successful treatment. Other parameters, such as the duration of the flash, are very important; the duration must be close to the Thermal Relaxation Time targeted.

In EFB beauté® machines, all treatment parameters have been optimised, tested and preprogrammed, in order to guarantee an excellent efficiency in treatment including: photodepilation, photorejuvenation, photosensitivity and anti-age.
