Details:
Studies show that blue light and red light at certain wavelengths
act together in clearing acne by combining antibacterial
and anti-inflammatory action, and that phototherapy with
blue-red light is an effective and safe treatment for acne
vulgaris.
Research...
As published in the British Journal of Dermatoloy, phototherapy with blue (415
nm) and red (660 nm) light was studied in the treatment of mild to moderate
acne vulgaris. After 12 weeks of 15 minute daily active treatments with a portable
light source, a mean improvement of 76% in inflammatory lesions was observed.
Investigators and patients favored the blue-red light therapy, with more patients
achieving marked improvement or clearance than in any of the other treatment
groups.
The researchers concluded that blue light and red light "act synergistically
in improving acne by combining antibacterial and anti-inflammatory action, rendering
phototherapy with blue-red light an effective and safe treatment for acne vulgaris."
Technically Speaking...
Research shows that propionibacterium acnes contain porphyrins, which can be
excited by blue (415 nm) light, leading to the killing of the bacteria. Studies
show that red (660 nm) light may have an anti-inflammatory effect on inflamed
skin pores. Based on European studies, the HappySkin Acne Light uses two
isolated light waves, a blue light that has been found to trigger a natural
process that kills the propionibacterium which settles in the follicles in
the skin and causes acne, and a red light that appears to positively affect
the inflammatory process.
What is Acne and What Causes It...?
Acne is a disease of the sebaceous hair follicle. The hair follicles, or pores,
in your skin contain sebaceous glands (also called oil glands). These glands
make sebum, which is an oil that lubricates your hair and skin. Under normal
conditions, sebum travels up the hair follicle and out to the skin's surface.
However, with acne, sebum is trapped within the follicle, clogging the follicle.
The bacterium that seems to cause acne is called Propionibacterium acnes
(P. acnes) and is present in everybody's skin, usually lodged in the hair
follicle. The clogged follicle becomes a breeding ground for bacteria. When
the sebaceous gland gets clogged, and sebum builds up inside the follicle,
P. acnes multiplies rapidly and can result in acne.
