What are LEDs?
LEDs are widely used in medicine; their use is based on the principle of photobiomodulation . Photobiomodulation is the activation of cellular metabolism through the use of light.
It is very widely used in medicine and is used in different fields. For example, in pediatrics , to treat neonatal jaundice ; it can also be used in neurology , in dermatology to improve acne , rosacea , and even in cancerology to improve certain side effects related to treatment.
In aesthetic medicine , I like to recommend it because it will stimulate the production of collagen . Which helps improve the quality of the skin , improve skin density and therefore fight against sagging .
Can LEDs harm eyesight?
A question that often comes up is: can LEDs harm eyesight? So the answer is yes and no . It all depends on the color of the light and the frequency of exposure .
Today, some studies show that blue light can damage the retina and promote a disease called age-related macular degeneration .
This is why I do not recommend using LED masks containing blue light at home if it is not equipped with protective glasses .
How long does it take to benefit from the effect of LEDs? And what are the purposes of using LED masks?
Patience is the key. LED masks should be considered for the long term .
Of course, it is illusory to think that with the use of an LED mask we will have the same effects as a surgical facelift . The goal of LED masks is to stimulate your collagen production , therefore improving the quality of your skin .
Light, thanks to photobiomodulation , will come to stimulate small cells, which we call fibroblasts , which are at the origin of the production of collagen . And these fibroblasts, over time, become a little lazy . So it's time to wake them up.
It takes 3 months of using LED masks to start benefiting from collagen production, but the effects on your skin color and brightness can be much faster.
How to choose your LED mask?
The easiest thing is to get advice from a professional because the different technical characteristics are not easy to understand. But a basic rule is that price does not make efficiency .
The different technical characteristics to take into account are the color of the light , which is called the wavelength , the fluence and the irradiance .
For the wavelength, it is necessary to favor combinations of wavelengths with red and infrared because they will stimulate the production of collagen .
A fluence of around 20 joules per square centimeter is very correct and an irradiance of around 40 milliwatts per square centimeter will allow you to have full efficiency for collagen stimulation .
