Understanding the mechanism of action of a LED lamp


Understand how to work the LED to go back to the basic principles of light

According to each color tested on patients who had different skin diseases, observations have been made. From these findings, we could deduce that for each (expressed in nanometers, or nm) wavelength, corresponding to different solid, we will find a specific indication.

Thus, it found that blue LED lights (with a wavelength between 400 and 480nm) have bactericidal properties and penetrating fongicidesen very weakly through the skin. They will be by examples indicated in the treatment of acne by specifically targeting certain bacteria that are responsible for (Propioni bacteri Acnes).

LED red, much more intense and penetrating, stimulate the synthesis of collagen and elastin by fibroblasts in depth and will therefore significantly reduce wrinkles and accelerate healing. It also noted that the lights in the red and infrared-emitting have Painkiller properties.

Lamp LED therapy has therefore gradually enters over the past decade in hospitals around the world. In the USA, University hospitals of Alabama and Wisconsin use it to treat mucositis post radio or chimioherapie with very encouraging results.

A study at the Hospital of la Pitié-Salpêtrière in 2006 on the treatment of stretch marks (both old and recent) by this method shows a straightforward improvement only after a few sessions of photobiomodulation.

Other studies have highlighted good results in treating wrinkles (concept of dynamic photo-therapie or PDT), larepousse hair and healing through including the synthesis of collagen and elastin by fibroblasts induced by red light.

A cosmetic doctor who offers in his armamentarium a complementary treatment by LED lamp is a real plus not only to accelerate the healing post-injections but also in addition to the treatments on offer for further guidance in aesthetic medicine and anti-aging
