The sebaceous gland is targeted by acne. There are many factors. One of them is Propionibacterium acnes a bacteria responsible for the severity and the persistence of acne.
This bacteria is sensitive to blue and red wavelength. Blue light can destroy directly the bacteria. Red light has a high anti-inflammatory potential.
The combination of Red and Blue wavelength improves the light therapy.
So comedos, pustules, redness and nodules disappear .With LED photobiomodulation the acne scars don’t appear.
One session by week during two months to initiate the treatment. After two session a month to maintain the results during two months. To stabilize the results is good to continue the light exposition during six months minimum.
The LED can be associated with other acts like microkystes extraction, peelings, photodynamic therapy to potentialize the results.
Classical treatments can be limited by side effects so LED therapy can offer a new way to treat and prevent acne disorders.
