What is Light Therapy?
If you’ve been doing your research on effective rosacea treatments, then you’ve already read more about light therapy than the average person. So let’s start with what light therapy is not; light therapy is not laser therapy, lasers take light and focus it (unnaturally) into a continuous beam.
Lasers work by destroying specific tissue, then depend on your body to clean up the mess. Lasers have the potential to do a great job – they also have the potential to do more harm than good. Light therapy poses no such risk.
Light therapy is not IPL. IPL takes non-laser light and blasts it at your skin at high intensity. Again, specific wavelengths of light are chosen to target certain cells or depths of skin, damage is done to those targeted areas, then your body cleans up the mess. Granted, the damage is usually less with IPL than with lasers, resulting in a less painful experience, and less drastic risks, but still, it’s not light therapy.
What light therapy is - Photobiomodulation
Light therapy is a branch of alternative medicine. It has been gaining more and more credibility in the conventional medical community, and has finally been accepted as a legitimate therapy and formally named “photobiomodulation.” Light therapy uses natural light of different colours (wavelengths) to cure, treat, and prevent a growing list of conditions, including rosacea. Light by nature is electromagnetic energy, traveling at roughly 186 thousand miles per second.
It does not need any help from man to have an impact. Here’s an example you might be familiar with: blue light therapy for jaundice. Blue light has been the standard treatment for neonatal jaundice for decades. These infants do not have to be bludgeoned with light for it to work. Instead, their delicate skin is bathed in gentle blue light for hours. Without any sensation or side effect, the light interacts with their blood through the capillaries in their skin, breaking down the bilirubin, so their body can clear it away. That is light therapy.
