Blue Light. (465NM±3NM)
Among its many other uses in various lighting applications, blue light is harmful to one of the bacteria that can cause acne, Propionibacterium Acnes. These bacteria, also known as P Acnes, cause skin inflammation, but thankfully the bacteria is very sensitive to blue light.
Using blue light can eradicate the P Acnes bacteria, which are normally found in the oil glands of the skin. Additionally, the added benefits of infrared light that can be obtained through the use of home blue light devices can help in causing the oil glands of the skin to shrink with treatment. Shrinking oil glands produce less oil, and less oil means less bacteria.
Over time, blue light skin therapy can have remarkable results in the eradication of acne. Repeated treatments eliminate the bacteria and decrease the inflammation associated with pimples and acne. After a number of blue light treatments, blemishes in the skin will begin to disappear, and your skin will go back to its normal, healthy appearance.
