What is ADENA?
The usual procedure for photodepilation of dark hair is not sufficient for white or blonde hair, due to the fact that these absorb almost no light. A different procedure was therefore developed and clinically tested by ADeNA Manufacturers in France in 2004 before being patented in 2005. This patent-protected procedure is exclusively reserved for users of ADeNA machines.
Why do we pulse the light? Two reasons:
- In order to obtain a real white light (spectrum adapted to the target before filtering), it is necessary to handle current levels of several hundreds of amperes in the tube ; the instantaneous powers are too high for a continuous operation.
- The second reason is linked to the required energy levels to get a good therapeutic result. To generate such energy levels, it is mandatory to stock this energy in a tank during the charging time, and then to send it by the means of the intense-light flash. A pulse mode operation is the best solution to reduce the volume and the weight of such machines.
It is interesting to know that the emission spectrum of the tube depends on the plasma temperature in the tube, and then on the current in the tube. It is therefore possible to adapt the tube’s emission spectrum to the target, by choosing the right current in the tube. The operator, when he selects the treatment configurations, chooses at the same time a light spectrum well adapted to the target.
Is there any clinical evidence that the Adena SPL can really treat white hair effectively?
Independant Clinical Studies by Dermscan France
The study was carried out on 14 healthy subjects, aged from 23 to 76 years (average age: 50 years), presenting blonde or white hairs. All presented precise inclusion and non inclusion criteria.
The results will astound you and these clinical trials will conclude the following:
Study of the density variation of light hairs (white and blonde) and dark hairs by images acquisition with videomicroscope Hirox® and analysis using Photoshop CS3® software. Analysis of the subjects' answers to a subjective evaluation questionnaire.
Under these study conditions, the photo-depilation process:
has significantly decreased the hairs density as well on the dark hairs (-75% after 4 sessions) as on the light hairs (-51% of white hairs and -27% of blonde hairs after one session). was appreciated by the subjects for its effectiveness (71%) and the absence of unpleasant feelings during the sessions (43%).
