LED Technology

A “LED” (Light Emitting Diode) is an electronic componant generating a specific electromagnetic wave (one type of photon) when stimulated by an electic current.

If the emitted wavelength is in the visible spectrum (between 400nm and 800 nm) the emission will be visible to the naked eye : Blue, Yellow, Red or Green depending on the wavelength.

If the emitted wavelength is not in the visible spectrum, the beam will not be visible. This is the case with the IR (Infrared).

A “LED” produces a low energy and athermic electromagnetic emission without heat generation.

Photothermal Effect

When the light waves emitted by the “LED” penetrate the skin, they are absorbed by the chromophores (Water, Haemoglobin, Melanin..to name a few) which instantly convert the photons energy into heat.

The heat beneficially stimulates a number of the skin elements. It also helps get rid of certain viruses and bacterium.


This is the real sought-after effect of the “LED” technology:

When applied at certain intensity and flashing at a certain frequency, the light waves penetrating the skin are absorbed by the chromophores of the cells and mitochondrions membranes.

Photo-stimulation is directly linked to the selected wavelength, the delivery intensity and flashing frequency of the light waves.

A wrong selection of only one of the above parameters will result in inadequate treatment results.
