Under normal circumstances, sebum, the oily substance made by the sebaceous glands, travels up the hair follicle and out to the skins surface. However, with acne, sebum is trapped within the follicle and skin bacteria multiplies within the clogged pores. Acne develops on those areas of the skin where sebaceous glands are most numerous: the face, scalp, neck, chest, back, and upper arms and shoulders. Acne typically begins in adolescence, although onset in the twenties or thirties is common.
One approach to treating acne is to target the bacteria that produces the inflammation associated with acne known as Propionobacterium Acnes, or P. acnes. P. acnes releases porphyrins, which are naturally occurring molecules in the body. When porphyrins absorb certain wavelengths of light, free radical damage is produced which destroys the bacteria.
Porphyrins absorb light best in the blue wavelength range 400 nm to 430 nm. A low intensity blue...
